Class Name Pesticide Specific Enforcement Method, CLOFENTEZINE
Method Title ANALYTICAL METHOD FOR RESIDUES OF CLOFENTEZINE IN FRUIT AND VEGETABLES
Method Date 1992/07/07
Method Type Quantitative
Scope and Application For analysis of clofentezine in crop matrices. Should work with most vegetable matrices.
Method Summary Fruit samplesare extracted into acetone and filtered. An aliquot equivalent to 40pct of the extract is removed and partitioned with hexane. The organic extract is rotary evaporated to dryness then reconstituted in hexane for clean up through a silica solid phase extraction cartridge. The clofentezine is eluted from the silica, evaporated to dryness, adjusted to the final volume and quantified using high performance liquid chromatography with UV detection at 268 nm.
