- GB/T 22260-2023 Determination of protein anabolic hormones in feeds by liquid chromatography-tandem mass spectrometry. This standard replaces GB/T 22260-2008 Determination of methyltestosterone in feeds by high-performance liquid chromatography-tandem mass spectrometry. This document describes the methods for determination of methyltestosterone in feeds by high-performance liquid chromatography-tandem mass spectrometry. Liquid chromatography-tandem mass spectrometry method for determination of protein anabolic hormones. This document is applicable to testosterone, methyltestosterone, bodiron, mehandrosterone, androstenedione, dehydroepiandrosterone, androstenedione in compound feeds, concentrated feeds, concentrate supplements, additive premixed feeds and mixed feed additives. Determination of nandrolone propionate, stanozolol, melengestrol acetate, and progesterone. The detection limit of methyltestosterone, stanozolol and melengestrol acetate in this document is 0.005 mg/kg, and the detection limit of testosterone, bodiron, mestandrosterone, androstenedione, dehydroepiandrosterone, nandrolone, propylene glycol The detection limit of nandrolone acid and progesterone is 0.02 mg/kg; the quantification limit of methyltestosterone, stanozolol, and melengestrol acetate is 0.01 mg/kg, and the limit of quantification of testosterone, bodiron, mesterone, androstene The limit of quantification for diketone, dehydroepiandrosterone, nandrolone, nandrolone propionate, and progesterone is 0.05 mg/kg.
