AppNote 225: Analysis of Forensic Samples by Pyrolysis Gas Chromatography Mass Spectrometry

Abstract

In this study, the GERSTEL PYRO was used for the pyrolysis of various materials that are relevant to forensic analysis applications, including paints, adhesives, and cosmetics. A GERSTEL MultiPurpose
Sampler (MPS) was used in combination with GERSTEL PYRO and GERSTEL Cooled Injection System (CIS 4), enabling efficient automation of the thermal extraction and pyrolysis of complex forensic materials. Fractionated and smart-ramped pyrolysis modes followed by gas chromatography mass spectrometry (GC-MS) analysis were used to determine important volatile additives and pyrolysates (from polymers) present in a diverse set of samples.
