Rapid Analysis of Trace Salbutamol and Clenbuterol in Pork Samples by Mass Spectrometry

A fast procedure based on internal extraction electrospray ionization mass spectrometry was developed for fast quantitative analysis of salbutamol and clenbuterol in pork tissue, offering high throughput (< 30 s), high sensitivity (LOD 6.2 - 9.8 ng kg−1) and no false positives.
