This document specifies a method for the determination of ammonia in tobacco and tobacco products using ion chromatographic analysis. It is applicable to tobacco, processed tobaccos, smokeless tobacco products and cigarette filler. The ammonia calibration range specified in the method is from 0,100 μg/ml to 10,0 μg/ml. This range correlates to 10 µg/g to 1 000 µg/g ammonia in tobacco. Samples with higher levels of ammonia can be diluted prior to analysis to bring the samples within the calibration range.
Abstract
Overview
ISO 21045:2018 - "Tobacco and tobacco products - Determination of ammonia - Method using ion chromatographic analysis" defines an analytical procedure to quantify ammonia (reported as ammonia from ammonium ion) in tobacco, processed tobaccos, smokeless tobacco products and cigarette filler. The method uses extraction into a dilute sulfuric acid solution followed by ion chromatographic (IC) separation and suppressed conductivity detection. The calibration range is 0.100 µg/ml to 10.0 µg/ml (equivalent to 10 µg/g to 1 000 µg/g ammonia in tobacco); higher-concentration extracts may be diluted into this range.
