A sensitive method for the determination of nitroamines in alcoholic beverages
- 21 Downloads
Nitrosamines in alcoholic beverages and malted barley were analysed by adsorption from the gas phase onto a porous polymer trap of Chromosorb 104 and subsequent desorption of the trapped compounds directly to a gas chromatograph fitted with glass capillary column and alkali-FID. The detection limit for NDMA was 0.05 μg/l in beer samples and 0.3 μg/kg in malted barley.
