If you are maintaining a legacy XPS system from the early 2000s, or if you have terabytes of old .spe files that need re-analysis, the xpspeak41 software download is still a vital tool. It is fast, free, and requires zero learning curve for those trained on it.

Usually a combination of Gaussian and Lorentzian (SGL). xpspeak41 software download

By resolving these overlapping peaks, researchers can determine: The precise binding energy (BE) of elemental core levels. The oxidation states of elements within a sample. If you are maintaining a legacy XPS system

Click Background . The program will automatically pick the low and high binding energy points, but you can adjust them if needed. Choose the background type— Shirley is generally recommended for XPS data. Click Accept . The program will automatically pick the low and

Fix or lock specific parameters—such as Peak Full Width at Half Maximum (FWHM), Gaussian-Lorentzian mixing ratios, peak positions, and area ratios—to maintain physical relevance during fitting.

If the application closes abruptly when you click optimize, your initial peak parameters are likely too far from reality.
