GC/MS People's Republic of China Entry-Exit Inspection and Quarantine Standards Replacing SN 0596-1996 Cereals and oilseeds export in SETHOXYDIM Residue Detection Gas chromatography - mass spectrometry exports-GC/MS Issued on. 2012-05-07 2012-11-16 implementation People's Republic of China The State Administration of Quality Supervision, Inspection and Quarantine released ForewordThis standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces SN 0596-1996 "cereals for export sethoxydim residues in." This standard compared with SN 0596-1996, in addition to editorial changes, the major technical changes are as follows. --- Modify the standard test method using gas chromatography - mass spectrometry method instead of the gas chromatography method; --- Modify the scope of the standard, the standard scope expanded from corn to corn, rice, soybeans, peanuts, and buckwheat; --- Modify the extraction and purification process, was extracted with acetonitrile, eighth and activated carbon, amino solid phase extraction (SPE); --- Measured by the lower limit of 0.04mg/kg was changed to 0.01mg/kg; --- Omitted sampling procedure. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Liaoning Province Exit Inspection and Quarantine. The main drafters of this standard. Jiang Weixin, Dongzhen Lin Tian Miao, Mike Sui, Bailing, even Xu. This standard replaces the standards previously issued as follows. --- SN 0596-1996. Cereals and oilseeds export in SETHOXYDIM Residue Detection Gas chromatography - mass spectrometry1 ScopeThis standard specifies the cereals for export sethoxydim residual gas chromatography - mass spectrometry and confirmation methods.
