Quick and Sensitive Analysis of Multiclass Veterinary Drug Residues in Meat, Plasma, and Milk on a Q Exactive Focus LC-MS System
15 Dec 2014In this application note, the Q Exactive Focus MS in combination with an UltiMate 3000 HPLC was used to create a variable data-independent acquisition method for the detection and quantification of 44 multiclass veterinary drug residues. This novel method proved to have the required LOD sensitivity, and ability to confirm identity using retention time, accurate m/z, isotopic ratio, and fragment ions to exceed the EU regulatory requirements (EC/657/2002).

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
