Cigarettes — Determination of benzo[a]pyrene in the mainstream smoke with a smoking regime according to ISO 20778 (intense smoking regime ) using gas chromatography-mass spectrometry (GC-MS) — Part 2: Using cyclohexane as extraction solvent ISO/DIS 23906-2

Scope

This document specifies a method for the determination of benzo[a]pyrene (B[a]P) in the total particulate matter of cigarette mainstream smoke with an intense smoking regime using gas chromatography/mass spectrometry (GC/MS) with cyclohexane as extraction solvent.
This method is specified using ISO 20778 smoking parameters. An alternative method for the determination of B[a]P is specified in ISO 23906‑1, with a different clean-up using methanol solvent.
