Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0590-1996 "export of meat and meat products for residues of 2,4-D butyl ester method."
This standard compared with SN 0590-1996, major technical changes are as follows.
--- Standard name from the "export of meat and meat products for 2,4-D butyl ester residues in" to "export meat and meat products 2,4
Butylate Residues by Gas Chromatography and Gas Chromatography - Mass Spectrometry ";
--- Expand the scope of the standard testing;
--- Deletion of a portion of the sample;
--- Improved sample preparation techniques;
--- Increased by gas chromatography - mass spectrometry method was confirmed;
--- Reducing the lower limit of detection, and detection of different objects, given the recovery of different substrates by adding different concentrations of the standard substance
range.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Shandong CIQ.
