In this application note we present an efficient and cost effective UHPLC-MS method using the ACQUITY Arc UHPLC System coupled with the ACQUITY QDa Mass Detector to screen and quantify carbamates in raw agricultural commodities, drinking and surface water, and soil, as an alternative to post column derivatization used in the Chinese GB standard (NY/T-761 2008).

Using DisQuE dSPE cleanup with a “dilute and shoot” sample preparation procedure, all analytes were detected using the ACQUITY QDa Mass Detector. No derivatization or time-consuming sample preparation was required, thus allowing for the rapid quantitation of carbamate pesticides on a single detector.
