Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces SN/T 1605-2005 "Import and export of plant products in cyanazine, fluroxypyr, atrazine, enemies, and ligulon residues
Test method for high performance liquid chromatography.
The main technical changes in this standard compared with SN/T 1605-2005 are as follows.
---Applicable matrix adds different types of plant products such as spinach, orange and Chinese cabbage;
--- Removed the "Sampling and Sample Preparation" section;
--- Sample pretreatment from the original neutral alumina filtration and C18 solid phase extraction column purification to composite strong cation exchange solid phase extraction
Column enrichment purification;
--- Optimized chromatographic and mass spectrometric conditions.

GB/T 6682 Analytical laboratory water specifications and test methods
3 method summary
The residual cyanazine, fluroxypyr, atrazine, dipyridamole, and ligulon in the sample were extracted with acetonitrile, concentrated to dryness under reduced pressure, and reconstituted with formic acid solution.
After purification and enrichment by a composite strong cation exchange column, the extract is sprayed with nitrogen to near dryness and then dissolved in acetonitrile-water. Liquid chromatography-mass spectrometry/mass spectrometry
Measure and confirm, the external standard method is quantitative.
