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
