Rapid Screening of β-agonists in Animal Hair by Thermal Desorption Electrospray Ionization Mass Spectrometry.

This method was the first to apply TD-ESI/MS to rapid analyse β-agonists in livestock hair which was proven to be accurate, fast and environmentally friendly. Because qualitative screening for each analysis was completed within approximately 1 min, it seems to contribute to prevent non-compliance animal-derived food flowing into the market.
