Scope

Scope: This document specifies the gas chromatography-mass spectrometry method for the determination of benzene, toluene, ethylbenzene, p-xylene, m-xylene, isopropylbenzene, o-xylene, and styrene in liquid milk. This document is applicable to the determination of benzene, toluene, ethylbenzene, p-xylene, m-xylene, isopropylbenzene, o-xylene, and styrene in liquid milk, including sterilized milk, pasteurized milk, fermented milk, acid milk, and modified milk. Main technical content: The benzene compounds in the sample are heated and volatilized by the headspace sampler and then enter the gas chromatography-mass spectrometry instrument. After separation by the capillary column, they are detected and quantified using the external standard method. Specifically, it includes the preparation of reagents and standards, analytical steps, instrument conditions, and result calculation and expression, etc.
