High Resolution Accurate Mass- and Triple Quadrupole- LC–MS Workflows for Today’s Veterinary Drugs Testing Laboratories

The screening and routine quantitation of veterinary drugs in diverse sample matrices are demanding applications that require laboratories to develop workflows that will not only address regulatory guidelines, but also enable detection of compounds beyond the scope of routine targeted quantitative assays.

This presentation will discuss two workflow solutions. First, we will present a new multi-class, multi-residue veterinary drug method using a new LC- triple quadrupole mass spectrometer system with high sensitivity and robustness for routine analysis. The method was evaluated using extracts of bovine muscle, salmon (fillet), and milk obtained using a modified QuEChERS sample preparation protocol. Secondly, examples will be shown to demonstrate how powerful HRAM MS technology can enhance quantitation and screening beyond targeted analysis and be a key problem-solving force in your laboratory.
