Pyrolysis Systems from CDS Analytical - Intelli Labs

Pyrolysis is the process of applying heat to large, complex molecules in order to break them into smaller, more analytically useful fragments. When coupled with GC, GC/MS, Direct MS, or FTIR, pyrolysis enables quantitative and qualitative analysis of vastly divergent sample types, without lengthy extractions or derivatizations. Many organic solids are unsuitable for analysis by any other means.
