Foreword
This standard replaces GB/T 20769-2006 "Fruits and vegetables 405 pesticides and related chemicals residues measured liquid chromatography
Spectrum - tandem mass spectrometry. "
This standard compared with GB/T 20769-2006, the main changes are as follows.
--- Pesticides can be measured by the 405 kinds to 450 kinds, an increase of agrochemicals negative ESI source detection;
--- Increasing the negative ESI source 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.
The main drafters of this standard. Pang Guofang, Li Yan, Individual Students Lian Jing, Cao Jing, Wang Wenwen, ZHENG Hong, Liu Yongming, Caoyan Zhong, Zhang Jinjie,
