How can we predict the chemical structure of polymer coatings by XPS analysis?

We have fabricated C4F8-co-AA polymer coatings by low-pressure plasma deposition. From XPS analysis we find the elemental composition and with the reconstruction of C1s spectra, we find the...

Bojidarka B. Ivanova

Mr. Iqbal,

Grams AI is commercially available with a presonal license and a hardware protection to a single machine (https://www.thermofisher.com/order/catalog/product/INF-15000). So, you need license.

But, I should mention that this is the best software for processing of spectroscopic patterns currently available. I am a Grams user and the comment is on the base on my experience with it. (NB! I have experience with more than 40 spectroscopic softwares).

If you are open to free alternatives, I would suggest you to look into MagicPlot, which can do non-linear curve fitting as well as multi peak fitting.
