摘要
采用顶空进样-气相色谱法同时测定胶粘剂中苯、甲苯和二甲苯。依据JJF1059.1-2012《测量不确定度评定与表示》，分析不确定度的来源，计算待测各物质在一定的浓度范围的不确定度，给出扩展不确定度，通过测量不确定度的评定，说明顶空进样气相色谱法同时测定胶粘剂中苯、甲苯、二甲苯结果的准确性。
Abstract
Detecting benzene, toluene, xylene in adhesive with headspace gas chromatography. On the basis of JJF1059.1-2012 " Evaluation and Expression of Uncertainty in Measurement ", analyzing the sources of uncertainty , calculating uncertainty of each substance in a certain concentration and also giving the expanded uncertainty. Finally, illustrating the accuracy of the simultaneous determination results of benzene, toluene, xylene in adhesive by headspace gas chromatography though evaluation of uncertainty in measurement.
