\"BabyRecently, scientists at Thermo Fisher Scientific<\/a> developed a method to detect and quantify multiclass veterinary drug residues in meats using state-of-the-art ultra fast chromatography with high performance triple quadrupole mass spectrometry<\/a>1<\/span><\/sup>. <\/span><\/span>The scientists involved in this demonstration adapted their analysis from a previous study by Mol et al.2<\/span><\/sup> which involved food samples spiked with analytes of interest, followed by mass spectrometry .<\/p>\n

One advantage of this protocol using high-performance liquid chromatography<\/a> (HPLC) is that very little sample cleanup is required. Samples of pork baby food were ground, diluted and shaken vigorously in a sonication<\/a> bath. The samples were centrifuged and the supernatant<\/a> was collected, filtered, and transferred into HPLC vials for analysis. Milk samples were prepared in a similar fashion. Liquid chromatography was performed using a Dionex UltiMate 3000 HPLC Stack<\/a>, Pump: HPG 3400RS, TCC3000 Autosampler OAS-3X00TXRS, and Accucore C18 columns.<\/p>\n

The high sensitivity of the TSQ Quantiva triple stage mass spectrometer<\/a> required only a small amount of the baby food and milk samples for analysis, without sacrificing the overall sensitivity of the analysis. Following mass spectrometry, TraceFinder software<\/a> was used to evaluate data and calculate results. TraceFinder provides a simple interface to locate positive hits and identify problems with a particular sample. This analysis was free from interferences, surpassed the current regulated maximum residue limits, and provided a simple method of accurately analyzing multiple classes of veterinary drugs.<\/p>\n
