BS ISO 23904:2020规定了使用ISO 20778吸烟参数，通过高效液相色谱荧光检测（HPLC-FLD）对选定酚类化合物进行定量的方法。选择的酚类化合物有:对苯二酚、间苯二酚、邻苯二酚、苯酚、对甲酚、间甲酚和邻甲酚。该方法适用于总颗粒物（TPM）产量在20 mg/支和45 mg/支之间的香烟。

BS ISO 23904:2020 specifies a method for the quantification of selected phenolic compounds by high performance liquid chromatography with fluorescence detection (HPLC-FLD) using ISO 20778 smoking parameters. The selected phenolic compounds are: hydroquinone, resorcinol, catechol, phenol, p-Cresol, m-Cresol and o-Cresol.This method is applicable to cigarettes with total particulate matter (TPM) yields between 20 mg/cigarette and 45 mg/cigarette.
