National Food Safety Standard — Determination of residues of 352 pesticides and their metabolites in plant-derived foods — Liquid chromatography mass spectrometry method
1 Scope
This document specifies the liquid chromatography mass spectrometry method for the determination of residues of 352 pesticides and their metabolites (see Annex A) in plant-derived foods.
This document applies to the determination of residues of 352 pesticides and their metabolites in plant-derived foods.
2 Normative references
The contents of the following documents constitute essential provisions of this document through normative reference. For dated references, only the edition cited applies. For undated references, the latest edition (including all amendments) applies.
GB 2763—2026 National Food Safety Standard — Maximum residue limits for pesticides in food
GB/T 6682 Water for analytical laboratory use — Specification and test methods
3 Principle
The test sample is extracted with acetonitrile. The extract is purified by dispersive solid phase extraction, detected by liquid chromatography mass spectrometry, and quantified by the external standard method.
4 Reagents and materials
Unless otherwise stated, analytically pure reagents and Grade 1 water complying with GB/T 6682 shall be used in the analysis.
4.1 Reagents
4.1.1 Acetonitrile (CH₃CN, CAS No.: 75-05-8).
4.1.2 Acetonitrile (CH₃CN, CAS No.: 75-05-9); chromatographically pure.
4.1.3 Methanol (CH₃OH, CAS No.: 67-56-1); chromatographically pure.
4.1.4 Sodium chloride (NaCl, CAS No.: 7647-14-5).
4.1.5 Ammonium acetate (CH₃COONa, CAS No.: 127-09-3).
4.1.6 Acetic acid (CH₃COOH, CAS No.: 64-19-7).
4.1.7 Anhydrous magnesium sulfate (MgSO₄, CAS No.: 7487-88-9).
4.1.8 Trisodium citrate dihydrate (C₆H₅Na₃O₇·2H₂O, CAS No.: 6132-04-3).
4.1.9 Trisodium citrate sesquihydrate (C₆H₅Na₃O₇·1.5H₂O, CAS No.: 6132-05-4).
4.1.10 Formic acid (HCOOH, CAS No.: 64-18-6); chromatographically pure.
4.1.11 Ammonium formate (HCOONH₄, CAS No.: 540-69-2).
4.2 Preparation of solutions
4.2.1 Acetonitrile acetic acid solution (99+1): Measure 10 mL of acetic acid, add to 990 mL of acetonitrile, and mix well.
4.2.2 Formic acid aqueous solution (0.01%): Pipette 0.1 mL of formic acid, add to 1000 mL of water, and mix well.
4.2.3 Formic acid in methanol solution (0.01%): Pipette 0.1 mL of formic acid, add to 1000 mL of methanol, and mix well.
4.2.4 Ammonium formate formic acid aqueous solution (2 mmol/L): Weigh 0.1261 g of ammonium formate, dissolve and dilute to 1000 mL with 0.01% formic acid aqueous solution (4.2.2), and shake well.
4.2.5 Ammonium formate formic acid in methanol solution (2 mmol/L): Weigh 0.1261 g of ammonium formate, dissolve and dilute to 1000 mL with 0.01% formic acid in methanol solution (4.2.3), and shake well.
