LC/MS provides an excellent alternative to conventional LC with UV, PDA or Fluorescence detection or GC/MS to measure polar pesticides in food matrices and in the environment.

We present UHPLC/SQ MS separation and detection method for a mixture of organophosphorus pesticides, carbamates, triazines and chlorinated pesticides.
