GERSTEL PYRO
Pyrolysis Techniques
Standard pulsed pyrolysis
- Generates results comparable with existing pyrolysis data
- Enables the use of pyrolysis GC libraries
- Pyrolysis of multiple identical samples in series under varying conditions
- Provides more in-depth information on unknown samples.
- Easy method development
- 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
