The use of beta-agonists as growth promoters in cattle breeding is forbidden in many countries for reasons of fair trade and consumer protection. In recent years the use of liquid chromatography (LC) tandem mass spectrometry (MS/MS) has been shown to be the method of choice for the control of beta-agonists. In this study an LC-MS/MS multiresidue analysis method is presented for trace analysis of 22 beta-agonists. A truly generic concept has been designed based on mixed-mode solid-phase… CONTINUE READING
