浩瀚气相色谱仪测定电泳漆中乙二醇乙醚质量分数GC7990

Tengzhou Xiangying Analytical Technology Co., Ltd. studied the determination of ethylene glycol in the electrophoretic paint by gas chromatography internal standard method, systematically analyzed the source of the uncertainty of the measurement results of the method, the uncertainty of the various components Evaluation and synthesis. The results show that the repeatability measurement of the peak area is the main reason for the uncertainty of the determination of the content of ethylene glycol ether. When the determination result of ethylene glycol ether is 3.306%, the expanded uncertainty is 0.300%. The mass fraction of ethylene glycol in the sample was measured as ωydm = 3.306% ± 0.300% (k = 2, P = 95%).
滕州市翔鹰分析技术有限公司对气相色谱内标法测定电泳漆中乙二醇乙醚质量分数的整个测定过程进行研究,系统分析该法测量结果的不确定度来源,对不确定度的各个分量进行评估和合成。结果表明,峰面积的重复性测量是影响乙二醇乙醚质量分数测定不确定度的主要原因。当乙二醇乙醚测定结果为3.306%时,扩展不确定度为0.300%。该样品中乙二醇乙醚质量分数测定结果表示为ωydm=3.306%±0.300%(k=2,P=95%)。
