摘要
目的:对以HPLC法测定菊花中绿原酸含量的测量不确定度进行分析,找出影响不确定度的因素,为评价检测报告提供科学依据。方法:用HPLC法测定菊花中绿原酸含量评估其不确定度,并根据《测量不确定度评定与表示》(JJF1059—1999)中有关规定评估其不确定度。结果:本次实验的不确定度评估为(0.369±0.0338)%。结论:发现本次实验的不确定度主要由样品的处理所引入。
Objective ： To find out the effective factors of uncertainty by analyzing the uncertainty of measurement in determination of the ehlorogenic acid in crysanthemum by HPLC and provide the evidence to evaluate the measurement. Method： Determination of the chlorogenic acid in cI-ysanthemum was carried out by HPLC and the uncertainty was appraised according to JIFI059--1999. Result： The uncertainty of this test was （ 0.369 ± 0.0338 ） %. Conclusion ： It is found that the uncertainty of this experimentis is mainly caused by sample handling.
