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.
