摘　要:分析液相色谱仪每项栓定项目检定结果的不确定度来源，以UV检测器为例进行分析，对液相色谱仪的主要几项检定项目检定结果的不确定度进行评定，其中泵流量设定值误差、柱温箱温度设定值误差、最小检测浓度、波长示值误差、定量重复性检定结果的相对扩展不确定度分别为0．64％、0．54％、5．32％、0．86％、1．38％。[著者文摘]
EVALUATION OF UNCERTAINTY IN VERIFICATION RESULT OF LIQUID CHROMATOGRAPHYLiu Zhijuan, Zhao Min, Xu Feng 1. CNGC Institute 53, Jinan 250031, China; 2. National Institute of Metrology,Beijing 10031, ChinaAbstract:The sources of uncertainty of verification result for liquid chromatograph were discussed. The detector UV was taken as example, uncertainties of several main verification results of liquid chromatographs were evaluated. The relative expanded uncertainties of pump flow enactment value error, columnition box temperature enactment value error, the least detection concentration, wavelengh value error, quantitation repeatabitity were 0.64%, 0.54%, 5.32% , 0.86% , 1.38% respectively.[著者文摘]
