Most recently formulated pesticides are smaller in molecular weight and designed to break down rapidly in the environment.


Use of a modified QuEChERS sample preparation procedure was fully evaluated for identification and quantitation of pesticides in lettuce using gas chromatography and ion trap mass spectrometry. Final results compared favorably to the reporting and detection limits offered by several worldwide agencies, demonstrating a robust and reliable solution for analyzing pesticide residues in lettuce.
