标准范围
ISO 29441:2010规定了一种在未稀释样品中,以2 mg/l至20 mg/l的总氮质量浓度,在各种类型的水(如地下水、饮用水、地表水和废水)内联紫外消解后测定总氮的方法。如果浓度范围的上限正好是下限的10倍(例如,0.2 mg/l至2.0 mg/l),则可以使用其他质量浓度范围。可通过改变操作条件来改变应用范围。
ISO 29441:2010 specifies a method for the determination of total nitrogen after inline UV digestion, in various types of waters, such as ground, drinking, surface, and waste waters, in mass concentrations ranging from 2 mg/l to 20 mg/l for total nitrogen, all in the undiluted sample.Other mass concentration ranges are possible, provided the upper limit of the concentration range is exactly 10 times the lower limit (e.g. 0,2 mg/l to 2,0 mg/l). The range of application can be changed by varying the operating conditions.
