SN/T 3814-2014 Determination of short chain chloroparaffin in rubber and plastic products - Gas chromatography tandem mass spectrometry (GC-MS/MS) method 1 Scope This standard specifies the gas chromatography tandem mass spectrometry (GC-MS/MS) method for determination of short chain chloroparaffin (C10-C13, containing 55.5% chlorine) in rubber and plastic products. This standard is applicable to the detection of short chain chloroparaffin (C10-C13, containing 55.5% chlorine) in rubber and plastic products using gas chromatography tandem mass spectrometry (GC-MS/MS) method. 2 Method summary The specimen is subjected to ultrasonic extraction, and the extraction liquid is purified by silica gel solid-phase extraction column, concentrated, diluted to constant volumes, determined using gas chromatography-tandem mass spectrometer, and then quantified by external standard method. 3 Reagents and materials Unless otherwise specified, all reagents used are chromatographically pure. 3.1 n-hexane. 3.2 Acetone. 3.3 Dichloromethane. 3.4 Standard short chain chloroparaffin (C10-C13, containing 55.5% chlorine), 100μg/mL. 3.5 Extraction solvent, n-hexane+acetone (1+1). 3.6 Elution solvent: n-hexane + dichloromethane (1+2). 3.7 Short-chain chloroparaffin (C10-C13, containing 55.5% chlorine) standard working
