Cigarettes. Determination of benzo[a]pyrene in cigarette mainstream smoke using GC/MS - Method using methanol as extraction solvent Ingestion-build-264231 Emission requirements for electrical and1 Scope This document specifies a method for the determination of benzo[a]pyrene (B[a]P) in the total particulate matter (TPM) of cigarette mainstream smoke using gas chromatography mass spectrometry (GC MS) with methanol as extraction solvent. This method is specified using ISO 3308 smoking parameters. An alternative method for the determination of B[a]P is specified in ISO 226342 with a different clean up using cyclohexane solvent and a shorter
