Xpspeak41 Software New! Download -

Developed by Raymund Kwok, is a free, fully featured software package explicitly designed for the analysis and deconvolution of XPS spectra. Despite the influx of modern, browser-based analysis suites, many researchers still prefer XPSPeak for several reasons:

The original XPSPEAK41 executable is very small (typically 3–6 MB) and should not require a complex installation routine.

XPSPEAK 41 was originally designed for older versions of Windows (such as Windows 98, XP, and 7). However, it can still run perfectly on modern systems like Windows 10 and Windows 11 by following specific configuration steps. Basic Installation Steps

XPSPEAK 4.1 remains one of the most widely used software tools for analyzing X-ray Photoelectron Spectroscopy (XPS) data. Despite being a legacy Windows application, its simplicity, powerful fitting algorithms, and zero-cost availability make it a staple in materials science and chemistry laboratories worldwide.
