Higher Confidence in Identification with QTRAP® LC/MS/MS Systems when Screening and Quantifying Pesticides in Fruit and Vegetable Samples

This note describes the use of QTRAP^® Systems coupled to liquid chromatography for the screening and identification of pesticides in fruit and vegetable samples. The selectivity, sensitivity, and accuracy of detection using QTRAP^® System and conventional triple quadrupole mass spectrometers are compared. The higher confidence of identification provided by QTRAP^® scans followed by library searches which minimize the potential risk of false positive and negative results is highlighted.
