What is ISO 23905 about?
ISO 23905 is a standard that covers the HPLC-FLD method for cigarette mainstream smoke which enables accurate determination of phenolic compounds in cigarettes and regulate their content.
ISO 23905 specifies a method for the quantification of selected phenolic compounds by high-performance liquid chromatography with fluorescence detection (HPLC-FLD) using ISO 3308 smoking parameters. The selected phenolic compounds are hydroquinone, resorcinol, catechol, phenol, p-Cresol, m-Cresol and o-Cresol.
ISO 23905 method is applicable to cigarettes with total particulate matter (TPM) yields between 1 mg/cigarette and 16 mg/cigarette.
