Foreword
The partial replacement of standard GB/T 20771-2006 "honey, fruit juice and wine in 420 kinds of pesticide residues determination by liquid chromatography -
Tandem mass spectrometry. "
This standard compared with GB/T 20771-2006, the main changes are as follows.
--- The determination of honey is separated from the GB/T 20771-2006 out, revision of this standard, and to redefine the standard
name;
--- Pesticides can be measured by the 420 kinds to 486 kinds, an increase of negative ESI and APCI source of positive and negative test for the presence of pesticide varieties;
--- Optimized pretreatment methods and increasing the negative ESI and APCI source source of positive and negative 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, Hebei University.
The main drafters of this standard. Pang Guofang, Li Yan, Individual Students Lian Jing, Zhao Shujun, ZHENG Hong, Liu Yongming, Caoyan Zhong, Zhang Jinjie,
Li Xuemin.
This standard was first published in 2006.
Honey 486 pesticides and related chemicals
Determination of residues of liquid chromatography - tandem mass spectrometry
1 Scope
This standard specifies the acacia honey, rape honey, linden tree honey, buckwheat honey, Date Honey 486 pesticides and related chemicals (see Appendix A and
Appendix E) residual amount of liquid chromatography - tandem mass spectrometry.
This standard applies to acacia honey, rape honey, linden tree honey, buckwheat honey, Date Honey 486 pesticides and related chemicals residues qualitative Kam
Do not also suitable for the quantitative determination of 461 kinds of pesticides and related chemicals residues.
461 kinds of pesticides and related chemicals quantitative determination of the standard method detection limit was 0.01μg/kg ~ 3.34mg/kg (see attached
Record A).
