摘    要:目的评定气相色谱法测定食用槟榔中环己基氨基磺酸钠(又名甜蜜素)的不确定度评定方法。方法根据气相色谱法定量测定食用槟榔中甜蜜素含量的测定原理,较全面的考虑整个测定过程的不确定度来源,建立结果不确定度评定的数学模型,并探讨其测定结果不确定度。结果在95%的置信区间下,当槟榔中甜蜜素含量为6.19 g/kg时,其扩展不确定度为0.18 g/kg, k=2。结论槟榔中甜蜜素的检测不确定度主要来源为标准曲线的拟合。

关 键 词:槟榔    甜蜜素    不确定度    气相色谱法

Abstract:Objective To evaluate the uncertainty of determination of sodium cyclamate (also known as cyclamate) in edible betelnut by gas chromatography. Methods Based on quantitative determination of sodium cyclamate in edible betelnut by gas chromatography, and more comprehensive consideration of the source of uncertainty throughout the measurement process, a mathematical model for evaluating the uncertainty of results was established and the uncertainty of its measurement results was explored. Results At the 95% confidence interval, when the content of sodium cyclamate in the sample was 6.19 g/kg, its extended uncertainty was 0.18 g/kg (k=2). Conclusion The main source of uncertainty for the detection of cyclamate in betel nut is the fitting of the standard curve.
Keywords:Areca catechu L    sodium cyclamate  uncertainty  gas chromatography
