Quantitative Analysis of Ractopamine in Beef using Automated Online Sample Preparation with Liquid Chromatography-Tandem Mass Spectrometry

Instrument Type: LCMSMS

Ractopamine is a phenethanolamine member of the family of b2-adrenergic receptor agonists (b-agonists). It has been widely used as a veterinary additive drug in livestock production to promote leanness in meat, accelerate average daily weight gain and improve feed efficiency. Recently, there have been growing concerns about the safety of meat containing ractopamine residues due to its potential health risks for humans. We describe a rapid and sensitive automated online sample preparation LC-MS/MS method to determine ractopamine in beef.
