摘要
通过对有机磷混合标准溶液配制和稀释过程中所存在的标准溶液本身的不确定度,容量瓶、移液管、溶液稀释及温度校正等引起的几个不确定度分量的评定和合成,得到了最终的扩展不确定度。表明移液管是影响标准溶液稀释最重要因素。
In this paper, the own uncertainty of the standard solution of organophosphorus pesticide and the uncertainties caused by the volumetric flask, pipette, solution diluting, temperature were evaluated, and the final expanded uncertainties were obtained. The results showed that the pipette was the most important factor of standard solution dilution.
