水中阴离子表面活性剂检测的不确定度分析

Uncertainty in the Test of Anionic Surface Active Solvent in Water

在进行水中阴离子表面活性剂检测时,对标准物质、玻璃器皿、回归直线的斜率和截距、试样的重复性、回收率的不确定度进行了评定,并将这些不确定度合成,最终估算了阴离子表面活性剂检测的总不确定度。

The uncertainties of the comparison substance, glassware, gradient and intercept of the regression line, reproducibility of sample and recovery ratio, during test of anionic surface active solvent in water, is assessed. All these uncertainties are summed up and an overall uncertainty of the test is assessed.
