The Electroantennographic Detector — a Selective and Sensitive Tool in the Gas Chromatographic Analysis of Insect Pheromones

A gas chromatographic detector is described which uses an insect antenna as a sensing element and permits the continuous monitoring of pheromones and other compounds with olfactory activity. In high-resolution gas chromatography allowing separations of positional and geometrical isomers, the electroantennographic detector gives precise information on the retention times of active compounds and permits the analysis of insect pheromones with exceedingly small amounts of material.
