Here is a fit program that I wrote for Igor

http://www.igorexchange.com/project/XPStools

In our lab, we are using a python script to convert the data into the 'igor-text' format before actually doing an analysis, however regular ASCII files just work fine with Igor (its just a little less convenient).

You can find free XPS peak fitting software.

Youcan use XPSpeak41, from data menu, choose to import (phi), and then select the file which should be having the extension asc. You need to have the first 4 lines as follow:

points20 (no space)

hxk-2

Su

1

If a problem replace the fourth line with 2

The xy data should be separated by dot (.) no other separation. If you have a problem, send the file and I will modify for you. Cheers.

you can use Peak Fit software or Orgin software for peak fitting...

I've had good experience with "fityk" for fitting XPS and other spectra. Great mouse interaction! Version 0.9.8 and older are free.

You might want to use FitXPS from Lund Uni

http://www.sljus.lu.se/download.html

it handles .txt or .dat file (you must have 2 columns in your txt/dat file, first for the electron energy, second for the intensity, due to some stupid bug it doesn't handle comas, so you'll have to replace all "," with ".", if any) This is a very simple software. The other popular, as far as I know, is CasaXPS, or smth like that (not sure if the name is 100% correct)

But in the end, most of the spectroscopists are facing the necessity to write their own plug-ins for Origin or Igor (probably the most popular spectroscopy data analysis software lately) for specific fitting of spectra

I agree with Min Cherry

I strongly recommend AAnalyzer Software since it is able to manage any type of TXT files, additionally it handles unto 12 files simultaneously. You can try it for free and there is a tutorial at the website: http://rdataa.com/aanalyzer/

I found this link from Cardiff University, which I would like to share with you:

http://www.cardiff.ac.uk/chemy/staffinfo/xpsaccess/software.html

It includes list of softwares for XPS, tutorial, database. and more.

Igor pro is great , at first it looks complicated but once you have learnt it. Then it is a great software to deal with. Also UniFit and CasaXPS are quite popular.

first i prepare a CSV(coma delimited) file of my data (text form)  using excel by Just pasting  data and saving as CSV(coma delimited). such files can be opened in Peak fit, Fityk,and any other XPS software.

It looks quite popular problem. I'm not alone. (Y)

Dear Professors, thank you for the answers. I have few doubts.

I request you, please clarify me. 

1. Is Fityk software can be used for XPS Peak fit analysis ?, Is it publishable standard?

2. What is the best fitting procedure, Gaussian or Voigt ?.

3. How to convert, text (.txt) files into vamas (.vms) files ?. Is there any software is available for this conversion?.

You should use CasaXPS software that can to deconvolute the XPS peaks.

Download CasaXPS here: http://www.casaxps.com/

In addition, you can use Origin Software to deconvolute the XPS peaks. But it does not recommend.

please anyone guide me how to do cationic fraciton by XPS data?
