| Abstract: | The uncertainty of nitrogen dioxide content in ambient air detected by Saltzman method was evamateo. Refolding process by measuring, using the measurement container, the concentration of standard solution, drawing standard curve, the sampling volume and the absorption solution volume of uncertainty affecting the measurement results of component analysis to indentify the key factors affected the measurement results. It would provide a significance of guidance to further optimize the detection method and improve the accuracy of tests. |
