## Abstract Packed capillary supercritical fluid chromatography coupled with thermionic detection was used for the selective determination of nineteen organophosphorus pesticides in vegetable extracts. The chromatographic behavior of some pesticides was studied using seven different stationary phas

## Abstract Methoximation of reducing oligosaccharides, combined with the additional derivatization of hydroxy groups, yields derivatives suitable for capillary supercritical fluid chromatography with thermionic detection. Detection limits on the order of picogramβperβsecond can easily be achieved.
The useful combination of capillary supercritical fluid chromatography with ultraviolet multichannel detection is demonstrated by the analysis of selected pesticides and herbicides. In this application the advantages of compound identification by ultraviolet spectrometry are appended to theseparatin
