Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0642-1997 "K residues in meat and meat products for export to kill."
The main technical differences between this standard and SN 0642-1997 follows.
--- Sample Extraction. solvent was changed to cyclohexane - ethyl acetate (1 1, volume ratio) to homogenization extraction method;
--- Sample purification. to GPC purification;
--- Chromatographic conditions. column HP-5 switch or equivalent person.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard is mainly drafted by. People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau.
The main drafters of this standard. Ni Xin Road, Iraqi male sea Yanghui Qin, Han Li, Zhou Yao, Zhu Jian, Yang Renqi, Cai Zeci.
This standard replaces the standards previously issued as follows.
