Abstract

Abstract A gas chromatographic procedure, using electron capture detection, has been studied and found to be applicable for determining 3 structurally similar fungicides, captan, folpet, and captafol, which are often found in combination in certain foods. Eight liquid stationary phases (AN-600, OV-25, OV-101, OV-210, OV-225, QF-1, SP-2401, and XE-60) were evaluated. A fluorosilicone stationary phase of moderate polarity, SP-2401, was best suited for column stability, response, resolution of captan and folpet, and freedom from on-column decomposition of the 3 fungicides.
