Supercritical fluid chromatography with electron-capture detection for the determination of agrochemicals

Abstract

The scope for supercritical fluid chromatography with electron-capture detection of several test agrochemicals was investigated using a carbon dioxide mobile phase. Operation with packed capillaries was found to be preferable to conventional (large inside diameter) packed columns. The detector employed was found to be suitable for the detection of the high-melting point fungicides captan and captafol.
