Pyrolysis Techniques

Standard pulsed pyrolysis
  • Generates results comparable with existing pyrolysis data
  • Enables the use of pyrolysis GC libraries
Sequential pyrolysis
  • Pyrolysis of multiple identical samples in series under varying conditions
  • Provides more in-depth information on unknown samples.
  • Easy method development
Fractionated pyrolysis
  • Multiple pyrolysis steps performed on a single sample at increasing temperatures
  • Provides more in-depth information, e.g. for multicomponent samples.
Thermal desorption with solvent venting and pyrolysis of the same sample
  • Thermal desorption analysis and pyrolysis is performed on a single sample resulting in separate GC/MS chromatograms
  • Sample is purged and cleaned using thermal desorption prior to the pyrolysis step
  • A clean pyrolysis profile is obtained without interfering contaminants that are unrelated to the macromolecular structure
  • Suitable e.g. for polymers in solution, enabling exact and reproducible sample amounts to be introduced
  • Automated drying of wet or humid samples, saves time by eliminating external drying step
  • Clearer and more accurate information is obtained from the sample
Split- or splitless operation
  • Accurate analysis results across a wide range of concentrations and sample amounts
  • Enables solvent vent mode for analyte concentration & sample clean-up prior to pyrolysis
  • Optimal transfer of analytes to the GC column depending on the analysis requirements
Selectable cryo trapping
  • Analyte focusing directly in the CIS liner provides improved peak shape for medium volatility range
  • Reliable results and more information, especially for volatiles and trace analytes
GC back flush in combination with pyrolysis
  • Interfering compounds can be kept out of the GC column and MS during pyrolysis
  • Back flush of unwanted high-boilers from GC column shortens GC runs and keeps the GC/MS clean
