What is Packed capillary supercritical fluid chromatography of organophorus pesticides: Selective detection and applications about?
## 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 phases. Addition of an organic modifier to carbon dioxide was needed to improve peak shape and reduce retention. Quantitation of organophosphorus pesticides in vegetable extracts showed good linearity. Extraction was performed in a one‐step extraction procedure using a water‐miscible solvent (acetone) and an organic solvent with limited water capacity (dichloromethane). Under these conditions a wide range of both polar and apolar pesticides can be recovered from vegetable extracts down to the 3–25 μg kg^−1^ level. The recoveries found ranged from 35 to 95% depending on the polarity of the pesticides.
