| Abstract: | On the basis of laboratory analysis, the uncertainty for determination of total nitrogen in water by continuous flow analysis was evaluated. In this paper, a mathematical model was established and the uncertainty source was analyzed, and then the components of uncertainty, synthetic uncertainty and expanded uncertainty were calculated. Finally a standard expression for determination result of total nitrogen was given. |
