本文件规定了以甲醇为萃取溶剂，采用气相色谱/质谱（GC/MS）测定卷烟主流烟气总颗粒物（TPM）中苯并[a]芘（B[a]P）的方法。 该方法使用ISO 3308吸烟参数进行规定。ISO 22634-2规定了一种测定B[a]P的替代方法，该方法使用环己烷溶剂进行不同的清洗，总分析时间更短。

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 22634-2 with a different clean-up using cyclohexane solvent and a shorter total analytical time.
