Quick and sensitive analysis of multiclass veterinary drug residues in animal products using a benchtop Orbitrap mass spectrometry system

摘要

Usually the analysis of veterinary drugs in animal products is a time consuming process with respect to sample preparation as well as mass spectrometric analysis. The quantitative analysis of 45 multi-class veterinary drug residues from meat products and waste usually involves not only different extraction methods either with SPE or LLE extraction, but also multiple sample injections. A new method, utilizing ultra fast chromatography and a bench top Orbitrap mass spectrometer is described in this study. The advantage to this approach is a short overall analysis time and to have a robust method to meet future regulation requirements, offering all options for additional targeted and non-targeted screening.
