A methodology based on the vapour phase (VP) generation of carbon disulphide from non-volatile dithiocarbamate compounds has been developed for determination of pesticide residues in foodstuff at low ppm levels. The method involves a selective reaction combined with liquid phase microextraction (LPME) and transmission infrared measurements. The use of a home made transmission cell improved the detection...
An analytical procedure has been developed for the simultaneous determination of carbaryl and 1-naphthol in water samples by means of in-field sampling and preconcentration on C 18 solid phase cartridges which, after drying are eluted on-line with a carrier flow of chloroform; carbaryl and 1-naphthol are determined by Fourier transform infrared spectrometry. Carbaryl is determined directly...
