ABSTRACT

A gas chromatographic method is described that is suitable for the determination of benalaxyl residues ranging from 10 to 0.1 micrograms/kg in several crops, must, wine, and water. The compound is extracted with acetone and purified either by partitioning between water and n-hexane or by passing the extract through an Extrelut column with n-hexane. Further purification is achieved by column chromatography on alumina. The active ingredient is finally determined by gas chromatography with nitrogen-phosphorus detection. Mean recoveries were > or = 95% in the various crops tested and in the 0.01-1.05 mg/kg fortification range. Standard deviations for each crop were < or = 6.5%.
