This section SN/T 1017 Part 7.
This section is in accordance with GB/T 1.1-2009 given rule drafting.
The partial replacement of SN/T 1017.7-2002 "cereals for export aldicarb, carbaryl, oxamyl, bendiocarb, pirimicarb residues detection
Test methods. " This section compared with the SN/T 1017.7-2002, the main technical changes are as follows.
--- This part of the increase of corn, wheat, soybean test sample matrix;
--- Change gas chromatography is liquid chromatography, liquid chromatography - mass spectrometry/mass spectrometry, lower detection limit;
--- Remove the sampling part;
--- Optimized pretreatment methods.
