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.

As an analogy, a Mass Spectrometer shatters compounds using electron impact, the compound is fragmented in a reproducible way, the ions are separated by the MS and the result is a spectrum which is both qualitative and quantitative. Pyrolysis works in much the same way. By applying heat to a sample that is comparable to the energy of specific bonds, the molecule will fragment in a reproducible way. The fragments are then separated by the analytical column to produce the chromatogram (pyrogram) which contains both qualitative and quantitative information. The number of peaks, the resolution by capillary GC, and the relative intensities of the peaks permit discrimination among many similar formulations, making pyrolysis a powerful tool in the identification of unknown samples.

CDS Analytical released the first commercial analytical pyrolyzer (Model 100) in late 60s, and has been proudly making world's best pyrolyzers for over 50 years. Our products have evolved through 6 generations and represent; the industries highest standard.​

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.

CDS's DISC module provides the easiest way to load your pyroloysis sample. 

The Drop-In-Sample-Chamber (DISC) is a novel accessory module for the 6000 series Pyroprobes. It transforms the horizontal sample loading probe used in traditional manual pyrolysis system to a convenient vertical loading system. The DISC saves your precious time by reducing the sample tube loading process. When used with the filler rod, the DISC helps to reduce sample preparation time by skipping the quartz wool insertion. The DISC chamber also isolates the pyrolysis sample tube from touching the platinum heating coil and can help to eliminate coil damages.

  • CDS resistively heated filament
  • Most convenient way to load pyrolysis samples
  • Minimum effort in routine maintenance
  • Upgrade to autosmapler
