摘 要:分析液相色譜儀每項(xiàng)栓定項(xiàng)目檢定結(jié)果的不確定度來源，以UV檢測器為例進(jìn)行分析，對(duì)液相色譜儀的主要幾項(xiàng)檢定項(xiàng)目檢定結(jié)果的不確定度進(jìn)行評(píng)定，其中泵流量設(shè)定值誤差、柱溫箱溫度設(shè)定值誤差、最小檢測濃度、波長示值誤差、定量重復(fù)性檢定結(jié)果的相對(duì)擴(kuò)展不確定度分別為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]
