GB/T 36497-2018 "Determination of Polychlorinated Biphenyls in Coatings" is applicable to the determination of eight specific polychlorinated biphenyls in coatings. After sample pretreatment, such as extraction and purification, the method employs gas chromatography-mass spectrometry for detection. Qualitative analysis is conducted based on retention time, and quantitative analysis is performed using the external standard method. The method specifies detection limits and precision, providing technical support for the control of such persistent organic pollutants in coatings.
