This standard describes in detail the method for the determination of short URL chlorinated paraffins (Co-Cs) in Spinning & weaving products by gas chromatograph-tandem mass spectrometry. The sample is added to n-hexane-acetone solution, subjected to ultrasonic extraction, then purified by graphitized carbon black solid phase extraction column and silica gel solid phase extraction column, and finally condensed, bandwidth evaluation, gas chromatograph - Tandom mass spectrometer (GC-MS/MS) for determination, and quantitative analysis by External standard method. Suitable for the determination of short URL chlorinated paraffins in various Spinning & weaving products.
