标准摘要
[中文适用范围]： 本文件规定了使用离子色谱分析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料。 该方法中指定的氨校准范围为 0.100 μg/ml 至 10.0 μg/ml。 该范围与烟草中 10 µg/g 至 1000 µg/g 的氨含量相关。 氨含量较高的样品可以在分析前进行稀释，以使样品处于校准范围内。 [外文原描述]： 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.
