The CDS Pyroprobe 6200 (pyroprobe) introduces samples that are not GC-amenable in their current state to the ISQ Single Quad GC-MS or TSQ Triple Quad GC-MS/MS. The pyroprobe heats the sample from ambient temperature to up to 1300 °C at rates of 0.01 - 20°C/ms. Fragments released in the process are focused and transferred to the GC for separation and identification via the ISQ or TSQ.
Most organic matrices in the environment are composed of material too large to volatilize at 300 °C and cannot be analyzed by GC/MS. Pyrolysis thermally extracts organic matter from complex matrices. Intact molecules are thermally extracted, or large molecules are broken into fragments that can be separated and identified by GC/MS. Pyrolysis is a destructive technique.
Analytical capabilities include:
- Microplastic characterization
- Lignin, cellulose, algal biomass, beeswax, peat, complex dissolved organic matter
- Fossils, amber relics, organic residues on archeological artifacts
- Residual monomers in synthetic polymers
- Glues, natural and synthetic rubber, paint
- Kerogen, coal, asphaltenes, heavy oils
Applications include:
- Microplastic materials characterization
- Fingerprint natural organic matter (NOM) in soil to understand soil formation processes
- Fingerprint soil organic matter to evaluate the biological stability of NOM
- Use of analytical pyrolysis to differentiate contamination from NOM
