摘要
分析和评估热解析-气相色谱法测定燃香产品燃烧后苯系物过程中可能引入的不确定度因素。建立苯系物不确定度数学模型,并采用A类和B类不确定度分别评定。根据不确定度评估结果,从仪器本身和实验操作的角度,提出了减少不确定度的方法和建议。
The uncertainty factors that may be introduced in the determination of BTEXs originated from combustion of incense by thermal desorption-gas chromatography were analyzed and evaluated.The mathematical model of BTEXs uncertainty was established,and type A and type B uncertainty was evaluated respectively.According to the results of uncertainty evaluation,the methods and suggestions for reducing uncertainty were put forward from the perspective of instrument and experiment operation.
