Pyrolysis is a thermal decomposition process of organic material at elevated temperatures in an anaerobic environment. It involves the cleavage of large complex molecules into smaller, more analytically useful fragments by the thermal energy.
|
|
CDS pyrolyzers can be used in universities, forensic labs, labs, government settings, and more for all your polymer research needs. They are also compatible with all major brands of GC/MS including: Agilent, Bruker, Thermo, PerkinElmer, and Shimadzu.

Thermal desorption encompasses two primary functions: sample collection / concentration and transfer to a detector.
Thermal desorption uses heat, (instead of solvent extraction), to release organic compounds from the adsorbent and transfer the entire collected sample to a gas chromatograph for analysis. This eliminates extraction time, (typically 12-24 hours), a solvent peak in the chromatogram (which can mask compounds of interest), and waste solvent disposal, an increasing expense in many labs. |

The Purge and Trap process involves purging the sample with an inert gas at the appropriate temperature and transferring the VOCs from an aqueous state to a vapor. After eliminating the moisture through the wet trap, the gas is then swept to an analytical trap that absorbs and retains the VOCs, where they are transferred to the GC for further analysis.
CDS Purge and Trap are designed around a few core concepts including EPA regulation compliance, reliability, expandability, dependability and competitive pricing. |
