IntroductionConcern about trace-level food contaminants is driving the demand for robust, rapid, and reliable methods for identification and quantitation of chemical residues and contaminants in food matrices. Usually, the detection methods such as triple quadrupole GC/MS and triple quadrupole LC/MS are aimed at a specific list of targets that are commonly found in food samples. These methods can be effective but may overlook any residues that are not specifically targeted. The approach to overcome this challenge is to perform untargeted screening of the sample intending to find as many compounds of concern as possible and allowing for retrospective analysis. Untargeted screening can be accomplished by analyzing the sample in full scan data acquisition mode.1,2 However, targeted triple quadrupole GC/MS (GC/TQ) analysis has an advantage of higher sensitivity and selectivity for the target analytes when compared to full scan analysis. The novel simultaneous dynamic MRM and scan (dMRM/scan) allows for acquiring both targeted dMRM GC/TQ data for target quantitation as well as full scan data for unknowns screening. Also, the simultaneous dynamic MRM and scan (dMRM/scan) deliver confident identification based on spectral library matching
