标准摘要
[中文适用范围]： 本国际标准规定了各种类型的水中，如地下水、饮用水、地表水和废水，经在线紫外消解后测定总氮的方法，质量浓度范围为 2 mg/l 至 20 mg/l，用于总氮，全部存在于未稀释的样品中。 其他质量浓度范围也是可能的，只要浓度范围的上限恰好是下限的10倍（例如0.2mg/l至2.0mg/l）。 通过改变操作条件可以改变应用范围。 注：可以通过载体溶液和校准溶液对样品盐度的灵敏度和适应性的变化来分析海水。 [外文原描述]： 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.
