Convert your raw XPS data from instrument-specific formats (such as VAMAS .vms , .txt , or .csv ) into an ASCII two-column format containing Binding Energy (eV) and Intensity (Counts).
This article will not only tell you where to get the safest but will also walk you through every step of the fitting process, from data import to final publication-ready output.

The remains an invaluable resource for researchers looking for a quick, unbloated, and free method to process photoelectron spectroscopy data. By ensuring you download from a secure academic source and configuring your modern Windows compatibility settings, you can effortlessly leverage this powerful tool to unlock critical chemical insights from your material surfaces. xps peak fit 41 new download
The XPS field continues to evolve, with new open‑source tools like lmfitxps offering Python‑based fitting with Tougaard backgrounds, Shirley models, and Doniach‑Šunjić functions. Meanwhile, commercial packages incorporate machine learning and automated peak assignment.
: The ability to fit different XPS regions simultaneously, which significantly reduces optimization time for complex analyses involving multiple elements or spin‑orbit split doublets.
: While originally built for Windows 95/98, it is generally compatible with Windows XP, 7, 8, and 10. University of Warwick Standard Peak Fitting Workflow Convert your raw XPS data from instrument-specific formats
: To ensure a physically meaningful fit, the software allows users to fix or link parameters like peak position, area, and Full Width at Half Maximum (FWHM).
Select the Gaussian-Lorentzian percentage (often set between 20% to 50% Lorentzian character for conventional lab-scale XPS systems).
What (like Origin or Excel) do you plan to use for your final figures? By ensuring you download from a secure academic
Create a new folder (e.g., C:\XPSPEAK ) and extract all contents into this folder.
The industry standard for standalone XPS processing (requires a license, but many universities hold site licenses).
Define the high and low binding energy limits for your specific region (e.g., C 1s, O 1s, or Fe 2p).
Export the fitted data back to ASCII to create publication-quality plots in software like Key Tips for Success
