TGA-IR-GC-MS Hyphenation

With this setup, it is possible to combine the analysis techniques TGA, FT-IR and GC-MS via coupling of the devices with a transfer line. The TGA-IR-GC-MS ‘Hyphenation setup’ is a powerful analysis technique to identify complex and unknown materials. Evolving gasses from the TGA are transported via a transfer line through an IR chamber. The gasses can be collected at any given time during the measurement to be injected in the GC-MS. The coupling can be varied to use the setup partially to improve it’s applications. Some of the applications of the hyphenation technique are:

  • The identification of additives, like plasticizers, in plastics
  • Determination of the primary components of a material
  • Analysis of unknown contaminations in a material, like fragrances or solvents
