摘要
通过分析烟火药剂中六氯代苯含量测量的不确定度来源,建立了气相色谱含量测定法的数学模型。对其中的标准溶液配置、测量重复性、样品准备等各个不确定度分量进行评估。计算得出实验测定结果的扩展不确定度为0.176mg/kg。
By analyzing the source of uncertainty among the determinate hexachlorobenzene content in pyrotechnic composition procedure, a calculation formula for the uncertainty in assay with GC was established. Each variable parameter included stand solution preparation, repetition measurement and sample treatment process etc among the procedure was analyzed. Results showed that uncertainty in the test was 0.176mg/kg.
