Locate the .VGX file in the experiment data tree. Either open the experiment by selecting 'Open Experiment' in Avantage, or double click on the .VGX file.

It is a very good idea to save the processing document as you analyze the data (Avantage may crash some times) - to do so, select 'Save Processing Document' and you analysis will be saved as a .VGD file.

XPS data processing guide

This section is intended as an introduction to the analysis of XPS data. Simple examples are chosen to illustrate the procedures. All actions performed with Avantage (version 5.498) during an analysis of a sample are shown.

In case you want to follow along with your own analysis, you can download the data from here (this file is a .zip file that has been renamed to .doc in order to be uploaded to LabAdviser, so download and rename to .zip and extract the files)

  1. Survey spectra analysis
    1. Open data
    2. Spectrum views
    3. View of data with several levels
