摘要
对空气和废气监测用氨溶液标准样品进行了制备和定值分析;同时对不确定度进行了评定。分别从标准样品的定值、均匀性、长期和短期稳定性等方面论述了不确定度的来源和评定方法;介绍了各种因素产生的不确定度以及总合成不确定度的计算方法。
Preparation and constant value of ammonia standard solution used in air and waste gas monitoring was evaluated. The uncertainty of certified concentration value of ammonia standard sample is described. The uncertainty components,between-bottle,long-term stability,characterization uncertainty were evaluated based on GB / T 15000. 3 Directives for the work of reference materials.
