摘要 目的建立HPLC法测定诺氟沙星胶囊含量的不确定度分析的一般方法。方法建立计算诺氟沙星胶囊含量的不确定度的数学模型,找出影响不确定度的因素,并对各个不确定度分量进行评估。结果计算各变量的不确定度,最终给出测量结果的扩展不确定度和置信水平。结论建立的不确定度评估方法适用于对HPLC法测定的诺氟沙星胶囊含量进行不确定度分析。 Objective To establish a general method for uncertainty analysis of the content of Norfloxacin Capsules measured by HPLC.Methods A mathematic model for calculating uncertainty was established,the factors influencing the uncertainty was determined and each component of the uncertainty was assessed.Results Each variable of uncertainty was calculated,and the expanded uncertainty and confidence lever were finally obtained.Conclusion The established method for uncertainty assessment is suitable for uncertainty analysis of the content of Norfloxacin Capsules measured by HPLC.
