【摘要】 依据GB/T 20388-2016《纺织品邻苯二甲酸酯的测定四氢呋喃法》,采用气象色谱质谱法对纺织品中的邻苯二甲酸酯质量分数进行了测定,以检出率最高的组分邻苯二甲酸二(2-乙基)己酯(DEHP)为例,通过对整个测量过程中不确定度的来源进行分析,建立了相应的数学模型,并对各个分量进行了评定,最终评定出了该方法的不确定度。更多还原

【Abstract】 According to the GB/T 20388-2016 "xtiles-Determination of the phthalate content-Tetrahydrofuran method", the amounts of the phthalate esters in textiles were determined by GC-MS. Taking the DEHP as an example, the source of uncertainty in the determination process was analyzed and the mathematical model was also established. The component of uncertainty was assessed, respectively, and the uncertainty was evaluated eventually.更多还原
