摘要
A UPLC-MS/MS method was established for the determination of fifteen kinds of β-agonists in feed.The analytes were separated on a column of BEH C18 100 mm×2.1 mm(i.d.) employing methanol as mobile phase A and 0.2% formic acid as mobile phase B(VA∶VB=1∶1).The analytes were determined by tandem MS under ESI+ and MRM mode.The linearity of fifteen kinds of β-agonists was range of 1-50 μg/L.The spiked recoveries of fifteen kinds of β-agonists ranged from 60% to 105%.The LOD and LOQ of the method were 0.1 mg/kg and 0.05 mg/kg,respectively.
