National Food Safety Standard - Determination of residues of 4 pesticides including glyphosate 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 4 pesticides including glyphosate and their metabolites (see Annex A) in plant-derived foods.
This document applies to the determination of residues of 4 pesticides including glyphosate 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 water. The extract is purified by a solid phase extraction column, detected by liquid chromatography mass spectrometry, and quantified by the external standard method.
4 Reagents and materials
Unless otherwise stated, only analytically pure reagents and Grade 1 water complying with GB/T 6682 shall be used in the analysis.
4.1 Reagents
4.1.1 Dichloromethane (CH₂Cl₂, CAS No.: 75-09-2).
4.1.2 Ammonium bicarbonate (NH₄HCO₃, CAS No.: 1066-33-7).
4.1.3 Ammonia solution (NH₃·H₂O, CAS No.: 1336-21-6).
4.1.4 Acetic acid (CH₃COOH, CAS No.: 64-19-7).
4.2 Preparation of solutions
4.2.1 Acetic acid aqueous solution (0.1 mol/L): Pipette 0.57 mL of acetic acid, dilute to 100 mL with water, and mix well.
4.2.2 Acetonitrile aqueous solution (0.1 mmol/L): Pipette 1 mL of acetonitrile aqueous solution (4.2.1), dilute to 1 000 mL with water, and mix well.
4.2.3 Ammonia solution (0.05%): Pipette 0.5 mL of ammonia solution, dilute to 1 000 mL with water, and mix well.
4.2.4 Ammonium bicarbonate ammonia solution (200 mmol/L): Weigh 15.81 g of ammonium bicarbonate, dilute to 1 000 mL with ammonia solution (4.2.3), and mix well.
4.3 Standards
The standards for the 4 pesticides and their metabolites are given in Annex A, with purity ≥ 95%.
4.4 Preparation of standard solutions
4.4.1 Standard stock solution (1 000 mg/L): Accurately weigh approximately 10 mg (accurate to 0.1 mg) of each pesticide standard, transfer to a volumetric flask, dilute to the mark with water, and shake well. Store in a storage vial (4.5.2) under light protected conditions at a temperature below 18 °C. The validity period is 1 year.
4.4.2 Mixed standard intermediate solution (50 mg/L): Pipette 500 μL of the pesticide standard stock solution (4.4.1) into a volumetric flask, dilute to 10 mL with water, and mix well. Store in a storage vial (4.5.2) under light protected conditions at a temperature below 18 °C. The validity period is 6 months.
4.4.3 Mixed standard working solution (5 mg/L): Pipette 1 mL of the mixed standard intermediate solution (4.4.2) into a volumetric flask, dilute to 10 mL with water, and mix well. Store in a storage vial (4.5.2) under light protected conditions at a temperature below 18 °C. The validity period is 1 month.
