PYROLYSIS GC/MS

 

A Perkin Elmer TurboMass Mass spectrometer equipped with Frontier Lab Double Shot
Pyrolysis PY – 2020iD accessory

Pyrolysis GC/MS analysis is an hyphenated analytical technique which can be applied for insoluble materials such as paint particles, rubbers, polymers, resins, adhesives, …
The material is thermally cracked at elevated temperature (400-600°C) in absence of oxygen.  The volatile pyrolysis products are transferred to a GC/MS apparatus for separation and identification.
In the pyrolysis device it is possible to work in a double injection mode.  Thermal desorption at moderate temperature (100-300°C) is first carried out to analyze additives as plasticisers, rest solvents, additives amd low molecular weight components.  This step can be considered as a thermal extraction.  Subsequently the pyrolysis experiment is performed at elevated temperature for complete thermal decomposition of the matrix.  Less than 1 mg (100-200 µg) material is required.

Applications

  • Analysis of unknown rubbers, adhesives, plastics, adhesives
  • Evaluation of batch to batch variations
  • Analysis of paint particles or insoluble residues
  • Screening of additives, plasticisers in polymeric materials
