Choose the appropriate background (e.g., Shirley for metals, Linear for simple cases).
If a specific runtime error persists, you can opt to run the software inside a lightweight virtual machine configured with an older version of Windows, or look for community-patched portable versions of the executable that have the necessary libraries bundled directly inside. Step-by-Step Workflow: Processing Your First Spectrum
Save your parameters in the native .xps file format so you can edit your work later. Use the export functions to save the raw data, background data, and individual peak component data to plot them into professional graphing software.
icon (depicting a red peak with blue deconvoluted peaks) and run it directly. Compatibility
Every peak in your fit should correspond to a plausible chemical state based on the sample’s known composition, preparation history, and literature precedents. As the XPS library guidelines emphasize: xps peak fit 41 new download

The you are fitting (e.g., C 1s, Ti 2p). The chemical states or materials expected in your sample.
If you attempt to open the help documentation within the application, modern Windows operating systems will block it because the legacy WinHlp32.exe engine is deprecated. To read the documentation, you can convert the .hlp files to PDF using online converters, or rely on community-created PDF manuals easily found via academic search engines. Step-by-Step Guide to Peak Fitting in XPSPEAK 4.1
XPS Peak Fit原生仅支持Windows。在Mac上使用需依赖虚拟机（如Parallels Desktop）或跨平台兼容层（如Wine）来间接运行。对于追求原生体验的用户，建议参考开源的 KherveFitting ，这是一款专为跨平台（Windows、Linux、macOS）设计的Python软件。 Choose the appropriate background (e
The industry standard for metallic and step-like electron energy losses.
The ability to fine-tune background parameters on both the low and high binding energy sides of a spectrum. 2. Flexible Line Shapes
Version 4.1 can import format files in addition to standard ASCII. Earlier versions also support some instrument‑specific formats, though the documentation recommends ASCII for maximum compatibility.
XPSPeak 4.1 is a free, widely used program for deconvoluting and fitting X-ray Photoelectron Spectroscopy (XPS) spectra Use the export functions to save the raw
Ensure you are downloading the software from an authorized university repository, institutional software portal, or the official developer mirror. Avoid third-party sketchy freeware sites to protect your system from malware. Look for the file named XPS_Peak_Fit_41_Setup.exe (or the equivalent package for your OS). Step 2: Installation Process Run the installer as an administrator.
Features adjustable Gaussian-Lorentzian mixing ratios to accurately model asymmetric or symmetric peak shapes.
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
Here are some common issues and solutions:
XPSPEAK 4.1 is a specialized software package utilized for the curve fitting of high-resolution XPS spectra. In materials science and chemistry, raw XPS data must be deconvoluted into individual chemical components to determine oxidation states, chemical environments, and elemental ratios.
Click the "Optimize" button. The software will run a least-squares minimization algorithm to adjust the peak parameters until the synthetic sum matches your experimental raw data line as closely as possible.
