T/YCXGH 003-2023 Determination of polycyclic aromatic hydrocarbons in smoke particulate matter of incense-burning products by gas chromatography-mass spectrometry
Basic Information
Scope
Scope: This document specifies the gas chromatography-mass spectrometry method for determining sixteen polycyclic aromatic hydrocarbons (PAHs) in the particulate matter of incense products. This document is applicable to the determination of naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, benzo(a)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-c,d)pyrene, dibenzo(a,h)anthracene, and benzo(g,h,i)perylene in the particulate matter generated by the combustion of incense products. Main technical content: This method specifies the gas chromatography-mass spectrometry method for determining sixteen polycyclic aromatic hydrocarbons in the particulate matter of incense products. Particulate matter of incense products is collected using a 1m3 sampling chamber and a filter membrane, and then extracted with a 1+1 (V/V) solution of n-hexane/methylene chloride. The extract is concentrated, diluted, and filtered before being analyzed using a gas chromatography-mass spectrometer (GC/MS). The compounds are identified based on their retention times and characteristic ions, and quantified using an internal standard method. 1.
