Use of a clean-up method to improve specificity in the analysis of foodstuffs for volatile nitrosamines
Abstract
An adsorption chromatography system is described for the clean-up of nitrosamines extracted from foodstuffs. The method is applicable to a wide range of food types and, by standardisation of technique and analysis of individual fractions of the eluate, improves specificity in the detection of nitrosamines by means of gas chromatography.
