Carbamates and organophosphorus (OPPs) pesticides are the
most widely used pesticides. Therefore, it has been necessary
to develop accurate analytical method for the identification and
quantification of OPPs and carbamate pesticides in fruits and
vegetables. Due to their physical chemical properties such as
thermal instability and polarity, carbamates are difficult or even
impossible to be analyzed usingGCtechniques without the timeconsuming
process of derivatization. Due to lower sensitivity
of LC/UV, HPLC with fluorescence detection by post-column
derivatization is the most widely used method for the analysis of
carbamate pesticides in foods [1]. Most OPPs are easily analyzed
by GC. Therefore, carbamates and OPPs are usually analyzed by
