Once the peaks are successfully fitted, Avantage calculates atomic concentrations using Scofield or custom library functions calibrated specifically to your instrument's transmission function. Best Practices for Peak Fitting in Avantage Achieving a low Chi-Squared ( χ2chi squared
Before fitting peaks, the inelastic background must be removed to isolate the core-level photoemission signals. Avantage offers three primary background types:
With an extensive built-in library of binding energies, the software helps researchers identify chemical states (e.g., distinguishing between Fe2+cap F e raised to the 2 plus power Fe3+cap F e raised to the 3 plus power ) with higher confidence. 3. Depth Profiling and Mapping
The platform features a 64-bit architecture capable of seamlessly handling multi-gigabyte datasets, multi-user project profiles, and real-time visualization fields. Core Architecture and Key Features
Aris stared at the word “Language.” He zoomed into the chemical shift data. The software had deconvoluted the Si2p region into a series of repeating spikes. Not random noise. Binary. But not 1s and 0s. The peaks represented a base-4 system, encoded directly into the oxidation states of silicon. Thermo Avantage Xps Software 24
: Integrates data from UPS (Ultraviolet Photoelectron Spectroscopy), REELS, and ISS within a single interface. Automated Charge Compensation
Beyond basic processing, Avantage includes specialized modules that save time and uncover hidden data patterns.
Insert a new peak component into your high-resolution window (e.g., O 1s or Fe 2p).
Ideal for deep core-level spectra where extrinsic energy loss is significant. Once the peaks are successfully fitted, Avantage calculates
Link doublet separations using standard quantum mechanics rules (e.g., P 2p doublet separation of ~0.86 eV, with a 2:1 area ratio). 4. Troubleshooting Common Software Issues Root Cause Network configuration error or hardware timeout.
The platform allows for "set-and-forget" experiment design, including multi-technique integration (e.g., combining XPS with Auger or ISS).
Furthermore, because Avantage utilizes an open-database architecture, it is straightforward to export data as CSV, VAMAS, or text files for collaborative review or further processing in other scientific software programs. Offline Processing and Data Accessibility
Generate a quantification table showing atomic concentrations. The software had deconvoluted the Si2p region into
: A standout feature is the ability to create automated sequences. You can set up a "recipe" for a multi-point analysis across a sample, and the software will handle the neutralization, acquisition, and peak fitting automatically.
Key features
Add components to represent distinct chemical environments (e.g., differentiating C-C, C-O, and C=O bonds in a carbon spectrum).
Non-destructive depth profiling can be achieved via ARXPS by changing the electron emission angle. Avantage features built-in mathematical models to reconstruct non-destructive depth profiles from angle-dependent data, tracking ultra-thin overlayers. Imaging and Mapping
