GC-MS thermal desorption-pyrolysis analyses

These techniques supplement the gas chromatography coupled with mass spectrometry analyses (GC-MS), to enable  to study all types of organic materials and polymers.

The sample  quantity required can be as low as about one milligram. Desorption at moderate temperature enables to analyse the additives and other substances not bound to the materials. Pyrolysis, i.e. high temperature thermal decomposition, reveals the actual structure of polymers and organic materials.

Some application examples:

  • Additives in polymers: plasticising or anti-UV agents, polymerisation residues, etc.
  • Biocides in leather,
  • Residual solvents
  • Corrosive degassing of materials: SO2, CS2, HCl, etc.
  • Characterising polymers and glues
  • Comparing polymer batches, ageing effect, UV irradiation, difference between suppliers
  • Composition of oils and lubricants
