猪尿中7种β-肾上腺素能激动剂残留检测的超高效液相色谱-串联质谱法研究

摘要

A UPLC-MS/MS method was presented to analyze 7 β-agonists residues in swine urine.The experimental results indicated that the recoveries ranged from 65%-111% and the RSDs were 3.07%-19.13%.The limits of quantification(LOQ) was 0.5 μg/L,and the detection limit(LOD)was 0.2 μg/L.
