Determination of imidacloprid, Acetamiprid Residues in Fruits and Vegetables High Performance Liquid Chromatography1 ScopeThis standard specifies the fruits and vegetables of Imidacloprid, high performance liquid chromatographic method acetamiprid residues. This standard applies to tomatoes, cucumbers, citrus imidacloprid, acetamiprid residues test.2 Determination2.1 Sample Preparation Samples will be taken from the original shrink separated 1kg, take the edible parts, crushed by the organization are divided into two, loaded into a clean container, as a sample, Sealed and marked with tags. 2.2 Sample preservation The sample was stored frozen at -18 ℃ below. NOTE. In the sample preparation process, should prevent sample contamination or the occurrence of the change of residue content. 2.3 Method summary Sample residual imidacloprid, acetamiprid extracted with acetonitrile extract was Florey silica column purification, concentrated, constant volume, use with UV detection High performance liquid chromatograph detector or diode array detector. 2.4 Reagents and materials Unless otherwise specified, the reagents were of analytical grade, water is distilled or deionized water. 2.4.1 acetonitrile. HPLC grade. 2.4.2 n-hexane. 2.4.3 acetone. 2.4.4 Sodium chloride. 140 ℃ baking 4h. 2.4.5 imidacloprid Standard. 96% or greater purity. 2.4.6 acetamiprid Standard. 96% or greater purity. 2.4.7 imidacloprid, acetamiprid standard solution. Accurately weigh an adequate amount of imidacloprid, acetamiprid standard, with acetonitrile formulated to 100μg/mL of Single stock standard solution, and then acetonitrile + water (30 + 70) diluted to a suitable concentration mixed standard working solution as needed. 2.4.8 SPE, Florey silicon column (Florisil), volume 3mL cartridges, filling 500mg. 2.5 Equipment 2.5.1 High performance liquid chromatograph. equipped with an ultraviolet detector or diode array detector. 2.5.2 oscillator. 2.5.3 Nitrogen blowing instrument. 2.5.4 rotary evaporator. 2.5.5 vortex mixer. 2.5.6 micro syringe. 100μL. 2.6 Determination of step 2.6.1 Extraction Weigh 25g sample (accurate to 0.01g), placed in 250mL conical flask with stopper, accurate added 50.0mL of acetonitrile, placed 2h, vibration After extraction 30min swing filtered through filter paper.
