1 Scope

This document describes the method for the determination of 19 veterinary drug residues in organic fertilizers by liquid chromatography-tandem mass spectrometry. This document is applicable to Amantadine (AMT), Sulfapyridine (SPD), Sulfapyridazine (SDZ) and Sulfamethoxazole in organic fertilizers (SMX), Sulfathiazole (STZ), Sulfamethazine (SMI), Sulfamethoxazole (SIZ), Sulfamethizole (SMT), Sulfamethoxazole Methane pyrimidine (SMZ), sulfa-6-methoxypyrimidine (SMM), sulfa-para-methoxypyrimidine (SM), sulfamethoxine (SMPZ), sulfachloropyridazine (SCP), Sulfamethoxine (SDO), Sulfamonomethoxine (SDM), Norfloxacin (NFC), Ciprofloxacin (CFC), Enno Determination of the residual amount of floxacin (EFC) and ofloxacin (OFC). The detection limits of this method are. sulfathiazole, sulfa-6-methoxypyrimidine, sulfamethizole and sulfachloropyridazine are all 20 μg/kg; its The remaining targets are all 5μg/kg.
