A robust, sensitive, and reliable multi-residue LC-MS/MS method workflow solution that uses the Thermo Scientific TSQ Altis triple quadrupole mass spectrometer provides analysis and quantitation of more than 160 veterinary drugs with the Thermo Scientific VetDrugs Explorer Collection solution in salmon (fillet), bovine muscle, and milk. The complete instrument and data processing method including SRM settings is included with the VetDrugs Explorer Collection start-to-finish workflow solution. In 17 minutes, the target veterinary drugs were detected and quantified in food matrices.
Forensic toxicologists need an economical solution to screen for a virtually unlimited number of compounds in urine. Here we present a method for screening using a dilute-and-shoot approach with the Q Exactive Focus mass spectrometer and Thermo Scientific ToxFinder software. For forensic use only.
Forty-four multi-class veterinary drugs of known concentrations were employed to demonstrate how the use of a generic variable data-independent acquisition (vDIA) method with wide MS/MS precursor isolation windows achieves sensitivity and selectivity comparable to data-dependent MS2 acquisition (using narrow isolation windows) in quantitative and qualitative small molecule applications. In addition, a full record of MS and MS/MS data for the measured sample fit for non-targeted and unknown screening purposes is delivered. vDIA is not available in the United States of America
To describe a new method for veterinary drug analysis, showing how the variable data-independent acquisition (vDIA) workflow achieves high sensitivity and selectivity, providing a complete high-quality data record of the measured sample. Quantitative analysis of the acquired data in combination with non-targeted and unknown screening is shown. vDIA is not available in the United States of America
The Thermo Scientific Dionex UltiMate 3000 LC system is applied for the analysis of metronidazole and its impurities. The separation was performed on a Thermo Scientific Syncronis C18 HPLC column using the method described in the EP 8.0 monograph. The results obtained for resolution and tailing factor exceeded the criteria stated in the EP. Resolution between impurity A and metronidazole was 6.9 (EP criteria of not less than 2.0) and tailing factor for metronidazole was 1.0 (EP criteria not more than 2.0).
