Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0586-1996 "Trump Residues in oilseeds and cereals for export methods."
This standard compared with SN 0586-1996, major technical changes as follows.
--- Remove the sampling step;
--- Modify the original sample before the standard treatment, the original criteria used chloroform extraction, and then purified by column chromatography on activated carbon -Celite
The method of the present standard to acetonitrile extraction, commercialization C18 solid-phase extraction (SPE);
--- Standard Scope increased peanuts.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. Jilin People's Republic of China Exit Inspection and Quarantine.
