    Pesticide residues: batches are sent to a third-party testing agency for testing, and are implemented in accordance with relevant standards

    Determination of content (HPLC): ≥98% based on our company ’s reference substance

    Test wavelength: 230nm

    Column: Hypersil ODS2 C18 5μ 250 * 4.6mm

    Mobile phase: acetonitrile: 0.02% ammonium acetate: triethylamine = 15: 85: 0.02ml

    Flow rate: 0.8 ml / min

    Configuration of reference solution

    Precisely weigh 10 mg of the genistein reference substance in a 25 ml volumetric flask, dissolve it in 15 ml of methanol with ultrasound. After cooling, dilute to a fixed volume and place in a 25ml volumetric flask, shake well.

    Preparation of test solution:

    Precise weighing: Equivalent to the amount of reference substance in the 25 ml volumetric flask. Use 15ml methanol to dissolve ultrasonically. After cooling, dilute to a fixed volume and place in a 25ml volumetric flask.

    Determination: Precisionly draw 15μl each of the reference solution and the test solution, and inject it into the liquid chromatograph for measurement, and record the peak areas of the reference and test products.

    Sample content Wx = A1 * C2 * Ws / A2 * C1
    C1 ------- Concentration of test product
    C2 ------- Control substance concentration
    A1 ------- Peak area of test product
    A2 ------- Peak area of reference substance
    Ws ------- (our company) the content of reference substance is 98%
    Wx -------- Test product content
