Gaussian curves are obtained from multiple XRD peaks via Origin. This is used to convolute complex peak.
Relevant answer
Answer
Dear Osama Ibrahim, XRD pattern is not simple as peak fitting. The information of the structure or atom inside the crystal is in the intensity, not the broadening, though the data were fitted with the profile function.
The structure factor quantifies the amplitude of X-rays scattered by a crystal, where the amplitude is determined by the position of the atom on the (hkl) planes (atomic coordinates), what atoms are on that ] atomic plane (atomic scattering factor), a vibration of atom about its equilibrium lattice site (temperature factor) and occupancy.

Answer
If this study refers to an oil rock core, it is difficult to say which is better and how journal reviewers view it. It is best to conduct an adsorption study, and then determine the CEM with the calculation of pores. If the number of pores according to the two methods coincides, then the article will be accepted for publication in the journal. Which method to calculate here does not matter.

Two days before, I received an email from the Journal. The reviewer asked me to answer this question and I did not understand the question. Could anyone help me on this? "Whereas the zero level of Fig.1 is not the same rather it fluctuates"
I am going to attach an image file please see it and give me a suitable suggestion.
Thanks for your precious time and valuable suggestions in advance.
Relevant answer
Answer
The problem might be your baseline. The signal to noise ratio seems to be high hence the peaks might not be peaks but results of poor baseline. You might combine the data of multiple reading to improve this graph maybe.

Dear Researchers.
I deconvoluted XPS peaks by Origin. Except for the Qualitative analysis of surface phases, I would like to perform Quantitve XPS analysis.
Is there any way to perform it by Origin?
Relevant answer
Answer
You can use Origin, but you need several additional constraits:
1) Your baseline is above the signal. Origin actually provides Shirley and Tougaard baselines that should allow you to avoid that. The CasaXPS manual section on baselines is rather helpful to understand what you are doing even if you don't have CasaXPS.
2) Be aware of the intermediate peak at 715-720 eV. If that is a real thing and not a subtraction artifact, it should be included and discussed.
3) The width of the components should be identical, assuming that the spectrum was taken in the constant analyzer energy mode.

Thanks in advance
Figure 4: (i) the image presented in panel (a) shows clear signs of measurements artifacts; (ii) Pale grey does not reproduce well; (iii) the labels presented on the axes of the images are not well aligned in the tick marks .; (iv) Verify the y- and x-axis scales.
Relevant answer
Answer
It seems to be artifact in Figure (a).It so-called "double tip" occurs when the probe tip has more than one point in contact with the sample. This most often occurs when the tip breaks and leaves a jagged point. Therefore, you can change the cantilever and then repeat the measurement.

I have standard data of Silicon sample and I want to subtract instrumental error (FWHM) from my sample. My sample and Silicon diffractogram are having peaks at different 2theta values (obvious). I am in confusion what could be the method to subtract instrumental error (any software or other way). Kindly explain in detail or attach the source (video, paper etc ) to learn it. TIA
Relevant answer
Answer
Rietveld refinement models the experimental XRD profile by accounting for the contribution of the instrument and of the crystalline phases present. You will need to know or measure some characteristcs of the instrument used that are used to calculate the instrument function -thus the contribution of the instrument to peak broadening, background and shape. You will also need a structure file for Si that is used to model the mineral contribution.
There are several software available for Rietveled, a few are open-source, here's a couple of my favorites:
All the above web-site also include tutorials and learning material on Rietveld Analysis.

I've been using OriginLab's Origin for years and I think that it's a great product.
I currently pay for it > 120 USD per computer per 1.5 years. As my group grows I'm interested in managing software expenses.
While Origin has diverse capabilities, I'm only interested in it for graph drawing and I prefer to do the analysis using other tools.
Any recommendation for lower cost substitutes? (for Win OS)
Thanks in advance for any input

BioVinci is a good choice. It's $25/one-year license and runs on Windows, Mac, (and Linux if I remember correctly). It's user-friendly by the way, and available plots are quite diverse. https://vinci.bioturing.com

I hope i can find explanatory answers for my 2 questions
1) When i plot data results obtained from UV-Vis experiments, I get confused which function i should to fit data points to the best fitted line and what does the fit infers. BTW, I always find that gaussian, boltzmann and asymptotic1 functions gives me the best fit.
2) Regarding Boltzmann function y = A2 + (A1-A2)/(1 + exp((x-x0)/dx)), does values for A1, A2, X0 and dx gives important meaning ? My plot represents fluorescence maximum as function of excitation wavelength.
Relevant answer
Answer
According to the Beer-Lambert Law, absorbance is proportional to concentration, and so you would expect a straight line.
Considering that you are using a UV-Vis then following the Beer-Lambert Law, absorbance is proportional to concentration, and so you would expect a straight line and therefore a linear fit might be the best option. However, bear in mind that at higher concentrations this is not always the case and the law breaks down.

I need to calculate the KD for enzyme-ligand using the quadratic equation as shown in the pic. Graph pad prism or origin software do not have these equation by default. However when I am trying to enter my own equation, both the software are not giving correct results. Perhaps I am making a mistake in the format of entering the equation. I shall be grateful if someone could guide me or  send me the prism file settings for same equation or tell me the software that has this equation setting by default.
Relevant answer
Answer
Hello,
I have an Origin equation formatted for this. 
Using Origin:
1) Create a new fitting function
2) Choose expression
3) Independent variable will be x, dependent will be y, parameter will be K (for Kd), constant will be A
4) In "function body" enter: 1/(1+(K/(x-0.5*(A+x+K-((A+x+K)^2-4*A*x)^0.5))))
5) On the top, switch over to constant, enter your constant value (for whichever concentration was kept constant)- you can change this each time if you have different constant values.
6) Hit "next" until you get to "finish"
You can now calculate your Kd with this equation. This will only work if you have a constant concentration, A, of either enzyme or ligand and then a changing concentration of the other for your x values. The K value that Origin calculates will be your Kd.
Let me know if this doesn't work!

I have two columns of data: diameter of nanoparticles and corresponding surface coverage area of each of them. I could easily obtain a frequency plot (diameter interval in x- axis and number of particles in y-axis) using MS excel, imageJ as well as origin. Now I would like to obtain a plot between diameter and surface coverage. ie, I need sum of surface areas of nanoparticles in each diameter interval in y axis. Please let me know about any program or script in Origin or imageJ which I can use to automate the process.

I would try pivot tables and pivot plots in excel. A bit of overkill for two columns, but if you have many entries it will make short work of it. There's a lot of online help, including instructional videos on how to use them.
