Annotation

In this project, major peaks identified in samples within the Ignitable Liquids Reference Collection (ILRC) and Substrate databases were tabulated to ascertain information on the chemical compound types present in ignitable liquids and pyrolytic decomposition products from substrate materials.

Abstract

A total of 221 major compounds were identified in the ignitable liquid and substrate records in the databases. Thirty-six of these major compounds were identified in both. The major compounds were grouped by compound type to provide a general characterization of ignitable liquids and substrates within the databases. ASTM E1618-14 designated classes were characterized by how often particular types of compounds were identified within each class. Identification of major compounds and how often they occur within a specified ASTM E1618-14 class and as substrate decomposition products may provide useful chemical characterization information.
