Trace analysis of agrochemicals by supercritical fluid chromatography

AbstractCapillary supercritical fluid chromatography was performed using solvent‐vented injection in conjunction with a thermionic ionization detector. Mixtures of organo‐nitrogen and phosphorus containing agrochemicals were chromatographed and detection of low picogram quantities was observed.

Solvent-vented injection in the analysis of agrochemicals by capillary supercritical fluid chromatography

Capillary supercritical fluid chromatography was performed with solvent-vented injection. Dilute samples of agrochemical mixtures were chromatographed and a study of detector response vs. quantity injected made.
