Application Note: Sensitive and Repeatable Analysis of Pesticides in QuEChERS Extracts with APGC-MS/MS
22 April 2014
Multi-residue pesticide analysis is challenging due to the low limits of detection required in a diverse range of food commodities. As there are currently in excess of 1000 pesticides in use, laboratories are under increasing pressure to broaden the range of pesticides determined in ever shorter turnaround times. Therefore, the analytical methods they employ need to be sensitive and robust in a wide variety of sample matrices. This application note demonstrates that the Waters Xevo TQ-S equipped with an APGC source provides a sensitive and repeatable solution for the analysis of pesticides in QuEChERS extracts of strawberry, pear, and spinach.
