本文件规定了使用离子色谱分析法测定烟草和烟草制品中氨的方法。 适用于烟草、加工烟草、无烟烟草制品和卷烟填充剂。该方法规定的氨校准范围为0100μg/ml至10,0μg/ml。该范围与烟草中的10μg/g至1000μg/g氨相关。氨含量较高的样品可在分析前稀释，使样品在校准范围内。

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.
