Foreword

This standard replaces GB/T 2795-1981 "frozen rabbit meat export BHC and DDT residues in." This standard and GB/T 2795-1981 compared to the major differences are as follows. --- Original method analytes BHC and DDT expanded to eight kinds of 24 kinds of organic chlorine, 3 and 14 pyrethroid acaricide Esters of pesticides; --- The packed column replaced with a capillary column; --- Gas Chromatography - Mass Spectrometry and confirmed the determination to replace gas chromatography - electron capture detector measures; --- Sample purification method using gel permeation chromatography and solid phase extraction method instead of the original method of sulfonation. The Standard Appendix A, Appendix B, Appendix C are informative appendices. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. Tianjin People's Republic of China Exit Inspection and Quarantine. The main drafters of this standard.
