GB/T 41524-2022 Determination of short chain chlorinated paraffins in toy materials—Gas chromatography-mass spectrometryForeword This document is developed in accordance with the rules given in GB/T 1.1-2020 Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights. This document was proposed by the China National Light Industry Council. This standard is under the jurisdiction of SAC/TC 253 National Technical Committee on Toys of Standardization Administration of China. Determination of short chain chlorinated paraffins in toy materials - Gas chromatography-mass spectrometry WARNING - Persons using this document shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This document specifies a qualitative and quantitative method for the determination of short chain chlorinated paraffins in toy materials by gas chromatography-electron capture negative ion chemical ionization source mass spectrometer. This document is applicable to the determination of short chain chlorinated paraffins with chlorine atoms greater than or equal to 5 in toy polymer materials. 2 Normative references No normative reference is listed in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 short chain chlorinated paraffins; SCCPs chloralkane mixture with carbon atoms of 10~13, with chemical general formula of CmH2m+2-nCln (m=10~13), and chemical abstracts registration No. (CAS): 85535-84-8 4 Principle Toluene is used as extraction solvent with Soxhlet extraction. The extract is separated by silica column or concentrated sulfuric acid, purified and concentrated, and then determined by gas chromatography-electron capture negative ion chemical ionization source mass spectrometer (GC-ENCI-MS) and quantified by internal standard method.
