Identification of pesticide residues in real matrices by combining retention indices and specific multidetection responses


HRC Journal of High Resolution Chromatography 19(2): 80-84
Identification of pesticide residues in real matrices by combining retention indices and specific multidetection responses
A previous paper reported the possibility of using the ratio between the responses of two different specific detectors to a single compound (detector response ratio, DRR) as an identification criterion for that compound, in combination with its retention index.This article gives some applications of DRR in the identification of some pesticides in four different fruits (apples, apricots, strawberries, and peaches) in a range varying from 0.02 to 1.3 ppm, by means of their ECD/FPD DRRs. After clean-up GC analyses were performed on a single column with dual parallel detection; a personal computer system was used for data analysis.
