目的建立离子色谱法测定血液等生物样品中氟乙酸钠类(氟乙酰胺)测量不确定度评价标准。方法采用《血液等生物样品中氟乙酸钠类(含氟乙酰胺)离子色谱测定法》,应用于测量不确定度理论分析该方法测量的不确定度。结果检验方法的扩展不确定度为:U=0.13 mg/ml。结论该检测方法的研究中进行不确定度的分析,能较为直观了解测试条件,建立分析方法能达到现行的相关标准及其灵敏度的要求,用测量不确定度对该方法进行有效可行性评估。 Objective To establish an evaluation standard for the uncertainty of measurement of sodium fluoroacetate (fluoroacetamide) in blood and other biological samples by ion chromatography. Methods “Blood and other biological samples of sodium fluoroacetate (fluoroacetamide) ion chromatography”, used in the measurement of uncertainty of the theoretical analysis of the method of measurement of uncertainty. The expanded uncertainty of the test results is: U = 0.13 mg / ml. Conclusion The method of uncertainty analysis in the study can be more intuitive understanding of the test conditions, the establishment of analytical methods to meet the current standards and sensitivity requirements, with the uncertainty of the measurement of the method of effective feasibility assessment.
