摘要: A method for the confirmation of tranquilisers azaperone and its metabolite azaperol, chlorpromazine, propionylpromazine acepromazine, haloperidol, xylazine β-blocker carazolol in porcine bovine kidney with LC-MS/MS was developed. Various solvents extraction techniques different ways clean-up were tested verified incurred pig from an animal study. The best efficiency reached by a mixture ammonia ethyl acetate overhead shaking without SPE clean-up. optimised twofold sample validated according to Commission Decision 2002/657/EC matrix-comprehensive in-house validation supported InterVal software, taking into account defined MRLs recommended concentrations. can be used residue control above-mentioned analytes food-producing animals accordance Council Directive 96/23/EC.
