FIA检测挥发酚结果的不确定度评定

Analysis of uncertainty in detecting phenol from water by using flow injection analysis

本文介绍了应用测量不确定度评定理论，使用FIA连续流动注射仪对水中挥发酚的不确定度进行分析．找出影响不确定度的因素，对不确定度进行评估，给出不确定度，如实反映测量的置信度和准确性。由于FIA连续流动注射仪可以测定水质分析中10多种元素，因此本方法也可以用于其他元素测定结果的评定。

The uncertainty in detection of phenol in drinking water by flow injection analysis was analyzed by using the theory of metrical uncertainty, find out the factors which influence the uncertainty, evaluate the uncertainty and give out the uncertainty of evaluation which faithfully reflects metrical credibility and accuracy. The method can also be used in analysis of uncertainty in detecting other ele- ments by flow injection analysis.
