摘要

通过建立数学模型,对固相微萃取—气相色谱联用法测量痕量苯的测量结果不确定度进行了评定。通过对影响不确定度的各分量进行分析,得出固相微萃取—气相色谱联用法测量痕量苯的测量结果不确定度为4. 8%。通过对各不确定度分量的分析可以得知气相色谱仪及色谱条件对测量结果的不确定度影响最大。
        By establishing a mathematical model,the uncertainty in the measurement of trace benzene by solid phase microextraction-gas chromatography was evaluated. Through the analysis of each component of the uncertainty,the uncertainty of the measurement results of trace benzene by solid phase microextraction-gas chromatography was 4. 8%. Through the analysis of each uncertainty component,it was known that the gas chromatograph and chromatographic conditions gave out the greatest impact on the uncertainty of measurement results.
