摘要
随着仪器的自动化程度越来越高,在仪器分析过程中,人工操作部分越来越少。所以仪器所处的实际状态水平,将对检测结果产生较大的影响。研究了不同离子色谱仪在相同色谱条件下,对同一样品的分离分析,并对测量过程中产生不确定度的影响因素:标准溶液浓度产生的不确定度、样品重复测定产生的不确定度、标准曲线线性拟合产生的不确定度、温度变化产生的不确定度等进行了分析,并对检测结果进行对比。
There is smaller amount of manual operation needed for an instrumental analysis with increasing instrumental automation level. So the influence of an instrumental status on the quality of testing results becomes bigger than ever before. In this work, the same sample was tested using different instruments under same chromatographic condition. Then the factors that create uncertainties in a whole determination process,which include concentration of standard solution, repeatability of measurement, linear fitting of the standard curve, and temperature variation, etc., were investigated and the results between different IC instruments were compared.
