what is the QC parameters in Analytical procedures of Plasma Atomic Emission Spectrometer .?

How do I find Miller coefficients?

I have "x'pert highscore plus (3.0.5)" software to plot my samples' XRD patterns. To check for the reference, software cannot find the exact match. So, I need to add Reference databases to the software. How can I do it?

What is the proper method for this particular version?

How were the limits of detection calculated in Plasma Atomic Emission Spectrometer ICPE ? According IUPAC recommendations or another method?

Hi Everyone, in 2018, Horiba came out a new instrument named Duetta, a 2 in 1 Fluoroscence & Absorbance Spectrometer. If you're using the instrument, it will be my pleasure to connect with you so we can discuss on optimizing the usage of the instrument and share some knowledge if our fields coincide. With that instrument, I was trying to determine my sample in ethanol as well as water. However, both EEM show distinct difference. If you've experienced or encountered similar issue, please let me know as I am struggling in looking for literature to approach this problem. Thank you for your help!

In spectrometers, I also usually saw the radiance (W/m2/nm) divided by E3 (photon energy^3) to get the emission rate in photons per unit spectral energy and per area. I'm getting s^3 nm^-1 m^-4 kg^-2 or s nm^-1 J^-1 m^-3 kg^-1and these units makes no sense for me. How do these units become equivalent to photons per unit spectral energy and per area? Thank you!

If I have 8 spectrometers together placed at different collection angles like looking a single point in a well at different locations . For the specific purpose I have to record signals from that single plasma from 8 different spectrometers placed at different locations with respect to laser plasma. In my present condition the spectrometers are not calibrated but I doubt even I calibrate it, it looks difficult to synchronize all. The reason of using 8 spectrometer because of having short spectral range 200 to 250, 250 to 300, 300 to etc.. upto 900 nm. and thus to frame spectrum in single picture all the spectrometer is placed at different angles, all the recorded spectrum is merged in a frame but the final spectrum is not true representation because one range spectra is not calibrated in the same way to other. The two atomic lines of different spectrometer can not be used for temperature estimation. What is best way to synchronize all the spectrometer together and get result such a way that whole spectral range data which is joined in one frame and get correct spectral data.

what is the cause of plasma color

plasma with the desired color can be produced

Changing the power supplied to a gas discharge increases the intensity of spectra lines, does this mean the degree of ionization increases

Difference between absolute and relative intensities?

How to record absolute or relative emission intensities using spectrometer?
