Foreword
This standard replaces GB/T 20772-2006 "Animals in determination of liquid color 380 kinds of pesticides and related chemicals residues
Spectrum - tandem mass spectrometry. "
This standard compared with GB/T 20772-2006, the main changes are as follows.
--- Pesticide can be determined by the 380 kinds to 461 kinds;
--- Increasing the negative group of test conditions.
The Standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix E is an information appendix.
This standard is proposed and managed by the State Administration of Quality Supervision Inspection and Quarantine of People's Republic of China.
This standard was drafted. People's Republic of China Qinhuangdao Exit Inspection and Quarantine, Shandong Agricultural University.
