Evolved Gas Analysis - METTLER TOLEDO

Evolved Gas Analysis

A thermobalance coupled to a suitable Evolved Gas Analysis (EGA) system allows qualitative information to be obtained for the gaseous reaction, or decomposition products, formed in a TGA experiment, as well as quantitative knowledge on mass changes. METTLER TOLEDO offer their expertise in the form of numerous articles, datasheets, webinars, etc., describing the various measurement techniques used when performing these types of analyses.

The advantages offered by each technique

    Application areas
  • Detection of small molecules(COx, NOx, SOx, H2O, HCl, etc.)
  • Residual solvents in active pharmaceutical ingredients
  • Detection of simple and complex compounds
  • Residual solvents in active pharmaceutical ingredients
  • Volatile molecules up to about 250 amu
  • Detection of small molecules ("permanents") is possible without MS
  • Detection of light and medium weight compounds by Micro GC/MS



More information on TGA-EGA can be found in our TGA-EGA handbook.
