Determination of dimetridazole in feedstuffs and pre-mixes by high-speed liquid chromatography
Abstract
A method is described for the determination of dimetridazole (1,2-dimethyl-5-nitroimidazole) in feedstuffs and pre-mixes by high-speed liquid chromatography. Dimetridazole is extracted from the sample with methanol-water (1 + 2). After liquid-liquid extraction into dichloromethane, an aliquot of the solution is injected into a high-speed liquid chromatograph.
