Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 1738-2006 "Importers in cereals and oilseeds tebufenozide residues test methods Gas chromatography-tandem mass
Spectroscopy "and SN/T 1770-2006" Importers Cereals by inhibiting insect hydrazine residues in liquid chromatography method for the determination. "
This standard compared with SN/T 1738-2006 and SN/T 1770-2006, the main changes are as follows.
--- Standard name was changed to "Determination of food for export tebufenozide residues";
--- Original SN/T 1738-2006 standard method used in the present second method;
--- Original SN/T 1770-2006 standard third method of the present law;
--- Increased liquid chromatography - mass spectrometry/mass spectrometry (LC-MS/MS) method was confirmed as positive samples (first law), and the scope of application
An increase of pork, chicken, milk, blueberries, oranges, spinach, onions, chestnuts Ren tea;
--- Delete the original standard sample parts.
