Summary
Once all regions are fitted, Avantage calculates atomic percentages using Scofield Relative Sensitivity Factors (RSFs) calibrated specifically for your instrument configuration.
Input the observed C 1s position and apply the correction globally to all screens. Step 2: Background Subtraction Thermo Avantage Xps Software 24
The hallmark of a powerful analysis platform is the ability to guide a user from initial experiment design to a final, publication-ready report. Avantage achieves this by being more than just a processing tool; it is a fully integrated data system. It provides complete control for all Thermo Scientific surface analysis systems, including the widely used K-Alpha, the high-performance ESCALAB Xi+, and the multi-technique Nexsa G2.
Accurate quantification begins with the baseline. Avantage provides several background subtraction algorithms, with and linear backgrounds being the most frequently used. The software automatically applies baseline adjustments based on the spectral regions you are analyzing, minimizing manual guesswork. 2. Energy Referencing (Charge Compensation) Summary Once all regions are fitted, Avantage calculates
Modern materials analysis often requires more than just XPS. Avantage seamlessly operates complementary techniques on the same instrument hardware, including Ultra-Violet Photoelectron Spectroscopy (UPS), Reflection Electron Energy Loss Spectroscopy (REELS), and Ion Scattering Spectroscopy (ISS).
Use the tool to flag surface elements.
Select an appropriate background type. For standard polymers and oxides, a is generally preferred. For transition metals, a Tougaard background often yields better results. Step 4: Peak Deconvolution (Fitting)
