Abstract:

In the present study, 7 carbamate pesticides in vegetables were determined using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), and this method was compared with commonly used HPLC with post-column derivatization method. Results showed that the analytes were well separated using both methods, which had good figures of merit. HPLC with post-column derivatization method is considered as a classical method having the advantage of good repeatability and the disadvantages of time-consuming operation, expensive derivative reagent cost and poor stability; in contrast, LCMS/MS, thanks to its short retention time, high sensitivity, simple and easy operation, and rapidity, is more competitive for determination of carbamate pesticides in vegetables.
