BS ISO 21045:2018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。该方法中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。交叉引用:ISO 5725-2:1994/COR 1:2002ISO/TR 22971:2005购买本文件时，所有当前可用的修改件均包含在购买本文件中。

BS ISO 21045:2018 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.Cross References:ISO 5725-2:1994/COR 1:2002ISO/TR 22971:2005All current amendments available at time of purchase are included with the purchase of this document.
