摘要
以采用靛酚蓝分光光度法测定空气中氨含量为例,分析了不确定度分量的来源及评定,确定了各不确定度分量值与灵敏度系数,给出了空气中氨含量测定的扩展不确定度.
Using the determination of ammonia in air sample by Indophenol-Blue Spectrophotometer method as example,the sources of uncertainty components was analyzed,and individual uncertainty value and sensitivity were evaluated,last the expanded uncertainty of determination of ammonia in air was given.
