Model prostaglandins were reacted with dimethylthiophosphinic chloride to form suitable derivatives using dimethylaminopyridine as a catalyst for supercritical fluid chromatography with thermionic detection. The high sensitivity of this phosphorus-selective detector makes it feasible to detect biolo
## 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.
## 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
