Analysis of β2-agonists in cattle hair samples using a rapid UHPLC–ESI–MS/MS method

2016

A simple and efficient method was developed for simultaneous analysis of five illegal residual β2-agonists in cattle hair. β2-Agonists were quantified by ultra high performance liquid chromatography coupled with electrospray ionisation tandem mass spectrometry operating in positive multiple-reaction monitoring mode. The method was validated as quantitative confirmatory method according to the EU Decision 2002/657/EC: instrumental linearity, specificity, precision, recovery, decision limit (CCα) and detection capability (CCβ) were evaluated. The recovery were greater than 90% and the method appeared suitable for the control of these β2-agonists in cattle hair samples with LOQ values between …
