GB/T 25001-2010 "Paper, board and pulps — Determination of seven polychlorinated biphenyls (PCBs)" specifies the use of gas chromatography and gas chromatography-mass spectrometry for determining the content of seven polychlorinated biphenyls, including PCB-18, in paper, board, and pulps. It is applicable to samples that can be digested using dry ashing or nitric acid wet digestion methods. After sampling and moisture determination, the sample is subjected to digestion and then analyzed using the specified instruments. The method defines the detection limit, recovery rate requirements, and result calculation methods to ensure accurate and comparable determination of polychlorinated biphenyl content.
