Questions related to IPA
Hello everyone, I hope you're having a great day. I'm currently a bit confused about whether I should use IPA or thematic analysis. I have already decided on thematic analysis, but I have stated that my research is based on a phenomological epistemology. Since thematic analysis is quite flexible, I would appreciate any suggestions on how I can align it with a phenomenological approach.
For background im conducting an interview based research with the aim to explore how individuals' interactions with social media shape experiences around body image among South Asians
I am trying to make very small gap (preferebly ~100 nm)electrodes. My recipe roughly is:
1. Cleaning SiO2 with acetone and ipa
2. Dehydration bake @180C for 1 min
3. Spin coat PMMA A4 @3k rpm for 1 min
4. Softbake for 5 min
5. Expose e-beam ~350 uC/cm2 (JEOL JSM)
6. Cold Develop MIBK:IPA= 1:3 (5C) for 1 min
7. Sputter Ti 1nm, then Pt 15 nm
8. Liftoff @60C acetone for 1 hour
For some reason, the metal is not coming off from the gap region. Any idea on why this is happening and what to change? Thanks.
I am currently writing my research proposal for my Occupational Therapy MsC. My research question is How is nature based volunteering experienced by adults living in cities? This has led me to think it should be a phenomenological study - however I think my philosophical underpinning is critic realism as I also want to identify what social/exonomic structures are supports/barriers. This has led me to think that a reflexive thematic analysis would be the best fit (rather than IPA) but I'm not sure if that's coherent?
Also as a novice researcher I have to realistic about what I can achieve so need a small sample size...
Any advice would be very much appreciated! TIA.
Good evening,
My IPA (Interpretative Phenomenological Analysis) research project involves conducting interviews in a different country and in a different language. Considering that I will need to account for cultural contexts and that the language may carry cultural meanings, would it be appropriate consider Poblete's (2009) five operations of translation in the Methods of Analysis section? Additionally, are there any translation tools available that could expedite the translation process?
Thank you.
Hi everyone, I am conducting an experiment which I am extracting substances into a IPA-water mixture. Since I am going to analyse the substances using GCMS, I need to somehow remove the water content from my solution.
I have searched and seen there are methods to do so such as by using extractive distillation but it is quite labour intensive and I also don't want to subject the compounds-of-interest to heat.
Therefore I am wondering whether there is another "easier" way to separate out the IPA-water mixture so that I can have the IPA layer to put into my GCMS.......
Thank you so much for your input.

Hello,
Im conducting a qualitative piece of research which ive positioned within a phenomenological grounding. I’m also utilising IPA as the framework for my data analysis. However, I’ve been asked to detail my analytical framework separate this to but I’m struggling to understand the difference between this and my data analysis approach. Any help would be greatly appreciated?
quick summary: I am looking for a way to slow down lift-off (1165 or acetone) for a given material system (changing materials to solve the problem is not possible)
This is a relatively general question. I have a given material system which presents low adhesion between semiconductor and metal (But imparts certain desirable properties). Lift-off is then not impossible but is completely done in under 5 minute and invariably leads to undesired loss of deposited metal. I would like to slow the process down (mainly for convenience and reproducibility). I am going to try IPA dilutions and active cooling as 2 approaches.
Has anyone ever tried these or other methods to slow down lift-off ?
The type of mixed method is sequential explanatory. I'm planning to conduct an experiment, and then explore how they experienced the phenomenon through IPA. How many participants would be enough for the quantitative part of the research? And do I have to include every participant during the qualitative part? Could I just select a few? 3-6, maybe?
I am conducting an interpretative phenomenological analysis, where I will be comparing the lived experiences of resilience among Syrian refugees residing in three different countries.
Taking into consideration the aim of the study as well as the complexity of the construct of resilience, I would like to explore it in a socio-ecological framework that views it as an interaction between multiple levels: individual, social, and macro.
However, given the inductive nature of IPA, I don’t know if it is possible to use a theoretical framework while conducting an IPA study. If yes, how to do it the best so I won’t affect the indictive nature of IPA? Can I use the framework in building prompt questions in the interview guide? Can I formulate my research question based on it? What will the analysis look like in this case?
People always use IPA or methanol as solvent for SAM molecular (such as MeO-2PACZ or Me-4PACZ) in inverted perovskite solar cells. However, the solubility of MeO-2PACZ or Me-4PACZ in IPA or methanol might be not so good (See Advanced Materials (2023): 2304415. ) Why does people not directly use DMF as solvent for SAM?
For spoken languages there is an International Phonetic Alphabet (IPA) created in the late 19th century as a standardized representation of speech sounds in written form. The IPA is designed to represent those qualities of speech that are part of sounds in spoken language: phones, phonemes, intonation... What about sign languages? Is it possible to create an IPA for these sign languages? Is it possible to create an IPA that represents the sign languages phones, phonemes and intonation?
Hello,
I'm trying to develop a LC-ESI-HRMS/MS method for the analysis of triacylglycerols in drying oils and paints, however I struggle with removing TAG contamination in blanks. After trying almost everything, I'm stuck.
I'm working with a Thermo Vanquish UHPLC, Waters 150 x 2.1 x 1.7 BEH C18 column and Thermo Orbitrap Exactive Plus. Mobile phase A: 60:40 H2O:ACN + 0.1%FA + 10 mM NH4Ac mobile phase B: 90:10 IPA:ACN + 0.1% FA + 10 mM NH4Ac
After a few injections of diluted oil samples I started to notice carry over occurring in blank injection. I first thought, this was caused by a weak washing solvent, however when changing to 100% IPA, peaks where still visible.
I have tried the following steps, without success:
- flushed the UPLC with different solvent mixtures according to the Waters LC-MS guide
- flush multiple times with 100% IPA (+ column)
- changing the column multiple times
- bypassing the autosampler/pre-heater/divert-valve to MS
- change the entire HESI-source by another HESI-source
- clean the ion sweep cone, ion capillary with IPA in ultrasonic bath and replace the O-ring
- increase the temperature of the HESI source to 'bake out'
- changing the mobile phase by fresh mobile phase
- changing mobile phase A to 80:20 ACN:H2O
- remove the FA in the mobile phases
- clean needle seat with IPA in ultrasonic bath
However, I still see signal when I run a zero injection while bypassing the autosampler, pre-heater and the divert-valve.
Any suggestions on what could be the cause/solution?
I'm using Giorgi method on my research design however my superviser suggested to us to use IPA. Can i use IPA while putting Giorgi's phenomenological approach on my research design? It really confused me.
I am conducting my MSc in Organisational Psychology and my thesis is centred on how managers support their teams various needs (across both short- and long-term and with regard to wellbeing or performance).
In my analysis, I am observing codes which differ in the managers style when meeting their teams short term needs compared with their long term needs as the managers talk differently / use different language to explain their actions.
Would this be an example of discursive analysis, and if so, is it then inappropriate to refer to if using a IPA methodology?
Many thanks in advance!
For my master thesis, I'm starting a research about siblings of adults with intellectual disabilities that live in a residential facility. My research is about how the siblings experience having a caregiving role for their brother/sister with a disability and sharing the caregiving with professional caregivers. It's not easy to share caregiving with professionals who have different views and not the personal relationship like the siblings have with their brother/sister with a disability. I want to do semistructured interviews with siblings and also focus groups with professional caregivers.
I'm not sure what analysis I would do because it is about experiences that make me look at IPA, but a thematic analysis would work too and is more available for beginners.
Can someone give advice? (English is not my main language)
Hi folks, I am currently troubleshooting the peak shape of my tailing tertiary amines in a targeted analysis of drug/drug metabolites by Agilent LC-QQQ-MS.
It is only the tertiary amines (amongst a whole variety of chemistries I am analysing). I am currently running neat standards to remove any matrix effects.
I run 0.1%FA + 10mM amm formate in water for A and 100% MeOH for B.
I have tried:
New column - old and new column have good peak shapes on a different LC-QQQ-MS.
Flushed all lines with IPA then IPA:MeOH:ACN:water, then following by Agilents nasty flushing soln which contains DCM:cyclohexane:ACN:IPA.
Replaced all solvents (wash and elution)
Tried new buffers with different lot numbers
Run in bypass mode
Tried different pH elution solvents
Tried different brand water and methanol
Changed solvent filters
Changed in line filter
Removed needle seat wash
There has been no improvement to peak shape with any of the above interventions...and its only my tertiary amines. Anyone else come across this type of issue before?
Cheers,
Catherine

Student researcher here, our topic is about the experiences of Parentified Young adults and was initially thought it would take a qualitative phenomenological approach. Now, we were advised to make it into an IPA. Im wondering what are the diff between the two.
Dear All,
I am trying to analyse targeted metabolites i.e Indole-3-acetic acid, IPA and ILA from fecal samples by HPLC. I have came across several extraction protocols for GC-MS but nothing on HPLC. Any help would be greatly appreciated.
I have microbiome sequencing data and I have analysed it to determine which taxa are up or down-regulated with my treatment, however, this doesn't really tell me much about the metabolic changes.
Is there anything I can use that is similar to the Qiagen IPA where I can place my metagenomics data and it can tell me if there are any changes in metabolic pathways?
Any links and tutorials would be greatly appreciated!
Water content in IPA is 1.7%. I want to decrease it to less than 0.5%. I have tried simple distillation and also distillation using an entertainer such as ethylene glycol. No positive results were observed.
Secondly, One anomaly observed during distillation of the first cut which we discard is having water content - 3.4% and 1st main fraction - 3%. I do not understand how this water content increased to 3% from 1.7%.
Actually, I need to measure insulation resistance of insulated metal sheet. For this I saw "wet insulation test using IPA".
Unfortunately, I have gotten non of the above answer. I hope this forum will be helpful.
Hello,
I am interested if there is another software that can give us holistic knowledge of differential gene expression (DGE) like how IPA produces.

Im writing begining to work on a piece of research that will ask about people's experince with psycedelic drugs and the steps taken to ensure positive exeprince/ minimise harm.
I want to conduct interviews asking questions about participants psycedelic experinces with an aim to find commonalities in thier experinces that could be used to inform safety protocols in the clinical use of psycedelics (psycedelic assisted therapy etc)
Because my research question focuses on peoples experince of a phenomena, i was assuming i needed to use IPA, but because i want to identify patterns across all (roughly five or so) participants whould it make more sense to use thematic analysis.
I've had a look at braun and clarke and to me that seems to indicate thematic analysis would be better suited
I'm working on the exfoliation of monolayer WTe2 on SiO2 substrate in order to create a heterostructure for transport measurements, and I'm having trouble getting thin layers. I tried various methods in the answers under the question "How to mechanically exfoliate tmds on SiO2", but it didn't work out. What I usually do is to put a piece of crystal on a tape and fold the tape many times so that the crystals are all over the tape. Then I press the tape gently on to a wafer that is either untreated, acetone + IPA cleaned, or O2 plasma cleaned. After that I heat the tape and the wafer to a 80 degrees hot for a few minutes. Finally I detach the tape from the wafer as slowly and as smooth as possible. All the processes above are done in a glove box. What I get on the wafer are just thick and small flakes (yellow) accompanied by smaller blue fragments.
Can anyone share a precise exfoliation process suitable for WTe2? Many thanks in advance.
Hello, I'm looking forward to conduct a qualitative research to understand the lived experience of girls and women who experience symptoms of Trance and Possession disorder and have been seeking support from faith-healers. I'm considering IPA for my study. Is it the best for such type of research? Sample size would be 3-6. Kindly guide. Thank you.
In GC-MS calculation,
[Area of GC chromatogram for IPA standard solution/ Molar Concentration of IPA in standard solution (mol/L] = [Area of GC Chromatogram of test solution / Molar Concentration of of IPA in test solution (mol/L]
How to convert the above formula to become
[Area of GC chromatogram for IPA standard solution/ Concentration of IPA in standard solution (ml/ml] = [Area of GC Chromatogram of test solution / Concentration of of IPA in test solution (ml/ml]
I prepared Cu Au core shell nanowires. After fabrication, they aggregated. Vortex has no effect while sonication causes them to break into short wires and rods.
How can I redisperse them in IPA or any other solvent?

I have samples solubilized in Ethyl Acetate, IPA, and small amounts of water (<10%). I was curious if the community had any input about plates and plate seals that would be compatible with that mixture and an autosampler for their eventual analysis on mass spec.
Thanks for any ideas!
how to seprate mixture of Acetonitrile 20% + IPA 80% ?
Hello,
We have been having contamination issues with our single quad LC-MS system (Waters Acquity Arc QSMR, Sample Manager FTNR, 2998 PDA, QDa). In particular, we observe an omnipresent species with m/z 100 across the entire chromatogram, m/z 271 and a series with m/z 295, 297, 299 (as well as 293, 296, 298 and 300, see pic) when the aqueous phase is between 100 and 20%, after that it seems to disappear. I should mention we are running either 10 minutes or 30 minutes gradients (5-90% ACN, only FA as additive for both MPs). I have tried to isolate the problem to either LC or MS, with inconclusive results. We have performed a thorough LC cleaning twice (washed with acidic mix, ammonia and IPA, then water @70C overnight, all LC-MS–grade from Biosolve), as well as MS source and ion guide cleaning (done by Waters engineer), but the problem is still there.
The strangest thing though, is that after the first round of LC cleaning the contaminants were gone (or below noise level) for about two consecutive days (see pics of spectra), and then all reappeared on day 3 (except for 271) when a new run was started, only difference being that I prepared fresh mobile phase (with commercial LC-MS–grade water and LC-MS–grade formic acid). After that I tried the cleaning procedure again, but this time with no success, although the general background signal did get much better.
We even installed a carbon filter between our (newly installed and checked) N2 tap and the MS inlet. At this point I do not know what else to try, Waters keeps suggesting that it's an LC problem, and they advice yet again another cleaning procedure (with 30% phosphoric acid), but I am a bit skeptical since we have tried 3 out of 4 of their advised cleaning mixes and protocols already.
Did anyone maybe encounter these same contaminant species? Or does anyone have suggestions as to what they might be and how to get rid of them? Since this is just a single quad, it's hard to say exactly from the m/z, but if I scan some of the " common contaminants" lists some of these masses match with either Triton or polymers (PPG or PEG), although I do not see the typical patterns for the latter. Any suggestion or tip would be greatly appreciated :)
Thank you



How do I convert volume ratios of IPA:water mixture of 2:1,4:1,5:1 to Mass ratios? Density of IPA is 0.786gm/cc. Can someone plz help?
I tried work out by taking a constant volume of 2ml total sample, so by taking 2 parts of IPA and 1 part of water, it makes 67% IPA & 33% water, so 67/0.786(IPA density) gives 85.241.
Is this correct?
Successive extraction of Pet.ether and chcl3 extract doesn’t soluble in familiar solvents (pet.ether, chcl3, E.A, methanol, ethanol, ACN, IPA, acetone, DMSO,DMF, water and acetic acid). Anyone can give the solution to dissolve the extracts?.
I have been experiencing consistent contamination of the pharmaceuticals ciprofloxacin, trimethoprim, carbamazepine, azithromycin and venlafaxine. The peak height remains the same with or without injection. and is predominantly seen when there is an addition of 5 mM ammonium formate. The standards I previously injected didn't exceed 2.5 ppb .
My method is:
(A) Aqueous : H2O + 0.1 % formic acid and 5 mM ammonium formate
(B) Organic: ACN + 0.1 % formic acid
Gradient:
Time % B
0 5
4 50
5 100
9 100
9.5: 5
The steps I have taken so far include;
- Multiple injections of 1:1 H2O: IPA (not going into column)
- Changing mobile phase (A: H2O + 0.1 % formic acid and 5 mM ammonium formate, B: MeOH
+ 0.1 % formic acid and 5 mM ammonium formate)
- Changing to a new column
- Replacing needle seat, injection needle and MS capillary
- Running an acidified cleaning mix (1:1:1, MeOH:ACN:IPA 1% formic acid) in the stead of my
mobile phase.
- Using an acidified multi-wash (1% formic acid) (A: 1:1:1 IPA:MeOH:ACN, B: 1:1 IPA: H2O, C: 1:1 ACN:MeOH)
- Ran the method with no injection
- Direct injection
- Deep source clean
- Injected acidified organic
- Changing capillaries
- Remade mobile phases with brand new formic acid and ammonium formate
Any help or thoughts on what to try would be a great help!

What causes the high Jsc in carbon-based perovskite solar cell <20 mA/cm2?
I bought a Molybdenum foil from the Goodfellow company and cleaned the substrate with ultrasonication for 20min each @RT with detergent, acetone, and IPA.
Still there is the polymeric residue unable to get rid of that
What if I use HNO3 will oxidize the substrate?
let me know if anyone has a recipe for cleaning
Dear colleagues,
I hope you are doing well. I am trying to get a uniform network of AgNWs on glass substrates from AgNWs dispersion in isopropyl alcohol (IPA), but I am finding some limitations. I use spin coating and drop casting methods. Before deposition, the glass substrate is cleaned by sonication in DI water with detergent, DI water, acetone, and IPA, respectively. After that, the substrate is dried by air and on a hot plate and treated by O2 plasma for 15 minutes to improve its hydrophilicity. Finally, drop casting or spin coating is performed. I tried many concentrations of AgNWs dispersion from 1 to 5 mg/ml. In case of spin coating, the density of the AgNWs on the substrate is very small and most of the nanowires are bent and/or have shorter lengths than the value provided by the supplier.
Please note that, different spin speeds (1000 - 3000 rpm) were used, but this didn't make a big difference.
For drop casting, the density of AgNWs is much bigger even at low concentrations, but there are many agglomerations and still the bending issue exists.
Also, the dispersion is stirred on a magnetic stirrer for (30 - 60) minutes before deposition.
Some SEM images are attached for clarification.
I'd be very grateful if you can give some advice to address the abovementioned issues.
Best regards,
Michael
We normally utilize EDTA, AgNo3, IPA, etc as scavengers for various reactive species in photocatalytic degradation studies and analyze the active species in the system.
I would like to know if there are any experimental techniques that we can employ to analyze the electrons, holes, superoxide radicals, and hydroxyl radicals generated in the photocatalytic degradation studies in the liquid samples.
Many anglers use fluorocarbon lines for their strength and abrasion resistance. However the hydrophobic surface makes it difficult for it to break through the water surface tension and it sticks on the surface. I'm after liquid or gel that I can smear onto the line that isn't water soluble but will give a hydrophilic surface to help the line sink. Any suggestions? I'm thinking along the lines of an hydrophilic polymer, such as polyester, dissolved in something like IPA?
Working in inclusive ESL classes (primary students) with varied learning difficulties, I have noticed that using the existing IPA information on Units' new vocabulary - found in our course books - students with learning difficulties were learning new vocabulary much easier while they improved significantly in writing and comprehension. So, I'm interested in a deeper research on this subject. Your experience and opinions would be much appreciated. Are you aware of similar research or research tools on the subject? Thanks in advance.
The starting point for Interpretative Phenomenological Analysis (IPA) is induction. It aims at filtering out theoretical and conceptual assumptions in order to allow the lived experiences of research participants vis-a-vis a phenomena to speak on their own terms. But, although IPA strongly emphasises an inductive process, many PhD students who choose IPA as their main methodological point of departure appear to make empirical and theoretical assumptions, as well as develop hypotheses, prior to embarking on their fieldwork (this is, at least, my experience). So, the question is, can IPA incorporate deductive processes, such as preconceived hypotheses?
While using Interpretive Phenomenological Analysis (IPA) in a Qualitative study, how can we represent data from several stakeholders other than the target group to explain different perspectives in a single study?
I will deeply appreciate your time and effort to provide any help, references and guidance.
Regards

I am trying to model the OCV of an electrochemical reaction where: ACT(g) + 2H+ + 2e- --> IPA(l), at T = 25 Celcius (Standard Temperature) and P = 19.6 KPa (P < Standard Pressure). The phase change occurs due to the low pressure and the differences in saturation properties between these substances. Any help is appreciated.
I am a new researcher currently doing experiments on perovskite solar cells.
Since I haven't got much experience in this area, I confront some questions regarding the experimental techniques.
I read the experimental sections from papers, but they usually only summarize the steps.
My questions are
1. For ETL, I use SnO2 dispered nanoparticles.
What is the difference between using IPA+DI water and using DI water only for dilution?
Do I need to stir to get rid of particles, or just sonication is enough?
Is filtration required after sonication?
2. As for the perovskite layer, I normally use FAPbI3 with small amount of MAPbr3 added.
Do I need a higher temperature or room temperature when I stir the mixture? and why?
3. For HTL, do I need to stir the mixture of spiro and chlorobenzene before adding additives and again after adding additives?
4. Lastly, does the thickness of film depend on the amount of solution dropped? What I read was it mainly depends on the rotation speed and time.
These may seem stupid questions, but I still look forward to answers..
Thank you!
Hello,
Im looking for good free alternatives to QIAGEN's IPA, could you suggest some similar software?
I'd preferably use a standalone version, not an online-based tool, it would also be great if it would be available on macOS.
I am currently doing a thesis using IPA for the lived experiences of student mothers. Can anyone share their ideas on how many respondents I need to have for the study? Thanks
i am creating a qualitative protocol to understand the feelings and experiences of employees returning to work after experiencing mental health issues whilst working remotely. the return to work can be remote or in-person. but my question pertains to whether using grounded theory in conjunction with IPA would be appropriate? one of my research questions is understanding employees feelings of using a hybrid model of work flexibility. so that is why i thought including grounded theory would be appropriate but im not sure.
Hello. I'm planning to do patch-clamp experiments mostly in current-clamp mode. Previously I had worked with Axon's amplifiers only, and for current-clamp mode best choice was Multiclamp 700B. But recently I discovered a Sutter's IPA/Double IPA which parameters looks very close to Multiclamp 700B. Does anyone has experience with this amplifier? What hidden bugs it has?
Thank you,
Viacheslav Viatchenko-Karpinski.
I am designing a study to gain insight into the experience of returning employees with a history of mental health issues. i want to understand how they feel about returning to work. is it ok to use interviews with IPA on returning employees and then thematic analysis on employees and family members of employees ? so IPA would only be on a subsection of the total sample. How will i justify this approach?
Hi,
I just start to work with microfluidics devices but the lab I work do not have access to any compressed air so I can not clean my cover glass really well before bonding with my PDMS.
I normally clean with acetone then IPA at the last step I dry them with tech wipes but there is still lost of dusts stays.
How can I achieve a better cleaning?
Thanks
I'm using IPA for my doctoral thesis as I'm evaluating the lived experience of postural orthostatic tachycardia syndrome. I've not done this type of analysis before so was wondering if NVivo would be a suitable programme to use? I've used it previously when I've conducted a thematic analysis but I'm not sure if there are other software options more suited to IPA. Any advice would be greatly appreciated.
Thanks
There is many polyurethane adhesives. 2k and 1k adhesives. Polyester polyols are most useful raw material for polyurethane adhesives.
Many monomers can be used in this polyols including IPA, AA, DEG, EG, NPG and others.
What is the most obvious role or function o each monomer in pokyester polyols?
For example IPA for heat resistance? NPG for adhesion or hydrophobic behaviour?
Hello, I run in to some troubles with the mechanical exfoliation of WSe2 and MoS2 on SiO2. I could get quite good flakes (~50um size) to direct exfoliate on PDMS, however 300nm SiO2/Si substrate does not work for me. The substrate is cleaned by ultrasonic in Acetone/ IPA/ DI water.
I read about some researchers also treat the substrate with Oxygen Plasma to remove organic adsorbents after the cleaning procedure I mentioned above. Is this a crucial step? If so, can I remove organic adsorbents by piranha?
many thanks in advance
I am currently doing an Electrospinning project, and I need to create an Hydroxyapatite solution that yields fibers. I plan to grind up HA into a powder and disperse it through Acetone (or IPA if I do not have enough Acetone). Can someone please tell me the steps on how I would approach this? I do not know if I have access to a sonication machine, but I do have a magnetic stirring machine. Any past experience would be appreciated.
IPA used is not anhydrous. Preparation is not carried out inside an inert glove box.
I prepared the MAI solution for the two-step deposition of Methylammonium lead iodide perovskite thin film.
Hello,
I am trying severalethods of analysis for several hydrophilic compounds and I seem to not have good signal for Ofloxacin.
I use ammonium acetate 5mM at pH 3.5 and ACN with 5 percent IPA in a 20 min gradient.
The Ofloxacin out of the 4 pharmas is the worst.
I used IPA and 5mM of ammonium acetate because it kept screwing the ESI and polymerizing making it no signal after 20 samples.
Any good method available?
Thanks!
I am preparing the PAA modified gold nanoparticle, but I have encountered a problem. According to the paper "Solvents induce phase separation for fabrication of Janus hybrid nanoparticles: A dissipative particle dynamics simulation", the solvent ratio of water and IPA is very important for the synthesis of Janus nanoparticles. I added the gold nanoparticle(in water) to IPA. However, the gold nanoparticle aggregated in IPA. I don't know why this happened? Did anyone encounter the same situation? I hope that someone may help me figure out this problem. I would be very grateful.
Hi all, I recently struggled with this question in my Viva and wondered if anyone has any thoughts of how one might answer this question? Many thanks in advance.
I want to rinse the wafer with IPA, DI water.
I use those two solutions as much as possible to achieve a spot-free surface.
However, I found that in many literature the sequence of use of IPA and DI water is different. IPA-DI water or DI water-IPA, which is correct?
I am using carbon/silver paste as adhesive for thin film deposition. After that, I want to remove the paste residue. It seems acetone + methanol + IPA does not work.Attempt to try piranha solution.
IPA is Interpretative Phenomenological Analysis.
My subjects are focused and direct lived experienced personnel.
However, I am not sure of the minimum sample to be taken. I hope can get some answers from experts.
Thank you.
Hello,
I wonder if you would be kind enough to help me. I’m a second year Occupational Therapy student and i’m currently writing my dissertation proposal. I want to do a qualitative student on ‘OT students perceptions of spirituality in practice‘. What is their understanding of the term? Do they think it relevant to OT?Have they supported individuals with this aspect of their well being during their placements? Do they feel confident and well prepared to meet these needs? I’m a little unsure about methodology and data analysis. Would the phenomenological approach be best? Would Interpretive Phenomenological Analysis (IPA) work with data from a focus group. I have read that IPA is not the norm for focus group data but that some see merit to this approach. I’m new to the world of research but very keen and excited to learn more. Thank you!
In one of my research studies, I'm looking forward to understand 'what does the term self-compassion mean to my participants, what do they think are the benefits associated with it etc'.
I hope to arrive at a conclusion regarding this concept for most of the participants which could then help in designing effective interventions.
I'm assuming that in this case, Thematic Analysis might be more useful. Would it also allow me to have more participants than IPA? Thanks
Hi all, I have been using lipid particles on UPLC with CAD and there is unknown contamination that is not going away. Contamination is detected starting around ~80%B in gradient elution. I did a few of the followings but still didnt resolve the problem.
1. Run Acetonitrile/IPA (2/1, v/v) 100% for 40 min which is Mobile Phase B
2. Run Acetonitrile 100% for 40 min
3. Clean the glasswares with Acetone (HPLC grade) and made fresh buffer B.
4. Run ACN/IPA/MeOH/Water (1/1/1/1, v/v/v/v) overnight
All these practices did not resolve the issue, and the contamination is continuouly detected.
Any other suggestions please?
While IPA is generally used in psychology and phenomenography in education, what would be the advantages of using one over the other in a research study of a relatively small (10-15) group ?
