>TABLE> >TABLE> Heading C (102): Reference method of measurement 1.The reference method of measurement to be used for determining pentachlorophenol in effluents and the aquatic environment is high-pressure liquid chromatography or gas chromatography with electron-capture detection after extraction by means of an appropriate solvent. The limit of determination(1) is 2 ìg/l for effluents and 0,1 ìg/l for the aquatic environment. 2.The reference method to be used for determining pentachlorophenol in sediments and organisms is high-pressure liquid chromatography or gas chromatography with electroncapture detection after appropriate preparation of samples. The limit of determination(1) is 1 mg/kg. 3.The accuracy and precision of the method must be ± 50 % at a concentration which represents twice the value of the limit of determination(1).
