## Abstract A multiβresidue gradient liquid chromatographic (LC) separation was developed for five Ξ²βagonists (fenoterol, metaproterenol, terbutaline, salbutamol and clenbuterol) in human plasma and detection was made using LC/atmospheric pressure chemical ionization mass spectrometry (LC/APCIβMS)
