Always attempt to fit the spectrum with the minimum number of components necessary. Adding excess peaks will lower the statistical error but often lacks physical or chemical meaning.
Kept equal or proportional across components within the same chemical environment. Step-by-Step Download and Installation Guide
Tip: Do not just chase a low Chi-Squared value. Ensure that every peak added corresponds to a logically sound chemical state expected in your sample material. 5. Exporting Results xps peak fit 41 new download
The download usually arrives as a compressed file archive (e.g., .zip or .rar ). Step 2: Extraction and Installation
For years, users with large multi-spectra datasets (e.g., depth profiles with 100+ spectra) complained about memory crashes. Version 41 is now fully , allowing it to utilize all available RAM. This means you can fit 500 peaks simultaneously without crashing. Always attempt to fit the spectrum with the
XPSPEAK 4.1 is a classic, freeware Windows application designed for the processing and curve-fitting of XPS data. Developed originally by Professor Raymond Kwok, the software allows users to decompose broad, overlapping XPS spectral envelopes into individual chemical components using Gaussian-Lorentzian sum or product functions. Key capabilities of the software include:
XPSPeak 4.1 is a widely used, free Windows-based application for visualizing and fitting X-ray photoelectron spectroscopy (XPS) data. While the original university-hosted download pages (like at CUHK) may no longer be active, the software and its documentation are still accessible through several reliable institutional and researcher-maintained mirrors.
