Avantage is designed to manage the entire lifecycle of an XPS experiment, from initial setup to final quantification: Instrument Control & Acquisition
: Manages hardware settings such as pass energy, step size, and dwell time. It also controls advanced features like the MAGCIS Dual Mode Ion Source
for switching between organic and inorganic depth profiling. Data Processing : Provides tools for calibrating binding energy
(typically using the C 1s peak at 284.8 eV) and performing background subtractions, such as the Shirley-type method Peak Fitting
: Includes automated and manual peak fitting models, allowing users to constrain parameters like doublet splitting, area ratios, and full width at half-maximum (FWHM). Quantitative Analysis
: Calculates elemental compositions (atomic percentages) using built-in sensitivity factors and instrumental transmission corrections. Optica Publishing Group Key Features for Surface Analysis

Thermo Avantage is the industry-standard software platform designed specifically for X-ray Photoelectron Spectroscopy (XPS) and surface analysis, developed by Thermo Fisher Scientific. As the digital backbone for instruments like the K-Alpha, ESCALAB, and Nexsa systems, Avantage provides an integrated environment that spans the entire analytical workflow—from initial instrument calibration and automated hardware control to sophisticated data processing and formal reporting. Core Architecture and Instrument Control
At its foundation, Avantage is built to manage the high-precision hardware required for surface science. It utilizes a digital instrument control interface that allows researchers to manipulate X-ray sources, ion guns for depth profiling, and electron flood guns for charge compensation. The software's "Instrument Manager" provides a real-time visual of the system vacuum, sample position, and source status, ensuring that even complex multi-technique experiments (integrating XPS with UPS, REELS, or ISS) can be coordinated within a single interface. Data Acquisition and Automation
One of the software’s greatest strengths is its focus on automation and productivity.
Sample Mapping: Users can import optical images of their samples and use "point-and-click" navigation to define analysis areas.
Template-Driven Workflows: For routine quality control, Avantage allows the creation of experiment templates. This ensures that acquisition parameters (such as pass energy, dwell time, and step size) remain consistent across different batches, minimizing human error. Thermo Scientific Avantage is the primary data system
Remote Operation: Modern versions of Avantage support remote data monitoring, allowing scientists to track long-running depth profiles or overnight automated runs from outside the laboratory. Advanced Data Processing
Once data is collected, Avantage offers a suite of mathematical tools to extract chemical information from the raw spectra:
Peak Fitting: The software includes robust algorithms for background subtraction (Shirley, Tougaard, or Linear) and peak modeling using Gaussian-Lorentzian profiles. This is critical for identifying chemical states, such as distinguishing between metallic iron and its various oxides.
Quantification: It automatically applies Relative Sensitivity Factors (RSF) to convert peak areas into atomic percentage concentrations, accounting for the specific transmission function of the spectrometer.
Depth Profiling: For thin films and layered structures, Avantage processes ion-sputter data to create composition-versus-depth plots. It can also perform Angle-Resolved XPS (ARXPS) processing to non-destructively map the top few nanometers of a surface. Chemical Imaging and Mapping
Beyond point spectra, Avantage excels in chemical imaging. It can reconstruct 2D maps showing the spatial distribution of elements or specific chemical states across a surface. This is particularly useful in microelectronics and failure analysis, where understanding the localization of a contaminant or the uniformity of a coating is more important than the average surface composition. Data Integrity and Reporting
To meet the needs of industrial and regulated environments, the software incorporates features for data traceability and "Audit Trails." Every change made to a spectrum—from a simple smoothing operation to a complex fit—is logged, preserving the original raw data. Finally, the "Report Designer" allows for the seamless export of publication-quality graphs and tables directly into Microsoft Word or Excel, streamlining the path from laboratory analysis to final documentation.
Researchers use Avantage 24 to trace fluorine (F 1s) and lithium (Li 1s) degradation in SEI layers. The software’s depth profile wizard handles the delicate subtraction of F KLL Auger peaks that interfere with Li 1s quantification. Improved Peak Fitting Algorithm : Utilizes advanced machine
Thermo Avantage XPS software is developed by Thermo Fisher Scientific, a leading company in the field of scientific research and laboratory equipment. This software is specifically designed to work with XPS (X-ray Photoelectron Spectroscopy) instruments, which are widely used for surface analysis of materials. XPS is a technique that can provide detailed information about the elemental composition and chemical state of the surface of a material.
Crucially, Avantage 24 retains the patented Knowledge View database—the industry’s largest repository of standard spectra and chemical state information. It also continues to support all legacy instrument formats (Theta Probe, K-Alpha, Nexsa), ensuring that existing users aren't forced to upgrade their hardware to benefit from the new software features.
