Fungicide residues. Part I. The detection, identification and determination of residues of quintozene in tomatoes, lettuces and bananas by gas chromatography

Abstract

A simple method for determining residues of quintozene in tomatoes, lettuces and bananas is presented. After extraction with hexane, quintozene is separated from interfering co-extractives by a partition process with dimethylformamide followed by chromatography on an alumina column, and is quantitatively determined by electron-capture gas-liquid chromatography. A confirmatory chemical test for quintozene is also described.
