This standard specifies the determination method of DDT content in coatings, which is suitable for the detection of DDT in various types of coatings. The standard is analyzed by gas chromatography, CG and gas chromatograph-mass spectrometry. The detection limit of gas chromatography, CG is 4.0 μg/kg to 10.0 μg/kg, and the detection limit of gas chromatograph-mass spectrometry is 2.0 μg/kg to 3.0 μg/kg. The standard aims to provide a reliable detection method to ensure the accurate determination of DDT content in paint products to comply with relevant environmental regulations and standards.
