标准摘要
[中文适用范围]： 本文件规定了采用环己烷萃取的气相色谱/质谱法（GC/MS）测定强烈吸烟状态下卷烟主流烟气总颗粒物中苯并[a]芘（B[a]P）的方法溶剂。 该方法是使用 ISO 20778 吸烟参数指定的。 ISO 23906-1 中规定了测定 B[a]P 的替代方法，并使用甲醇溶剂进行不同的净化。 [外文原描述]： 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.
