Adding more confidence to sensitive quantitation in complex foods by triple quadrupole GC/MS (GC/TQ)

Concern 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. Agilent describes the use of the novel simultaneous dMRM/scan (dynamic multiple reaction monitoring/scan) data acquisition mode for reliable identification and quantitation of pesticides in challenging food matrices. Simultaneous dMRM/scan mode eliminates the need to reanalyze the sample in each data acquisition mode separately, enabling retrospective analysis, yet demonstrating comparable performance for quantitation to dMRM only mode. Explore an outline of this method using the Agilent 8890/7000E and 8890/7010C triple quadrupole GC/MS systems (GC/TQ), for spinach, walnut, and cayenne pepper extracts.
