| 摘 要： | 研究了没食子酸辛酯标准样品的制备、均匀性和稳定性及其定值试验。将没食子酸辛酯工业品用无水乙醇溶解,再用纯水稀释后重结晶,得到高纯度的没食子酸辛酯标准样品。没食子酸辛酯含量测定采用液相色谱面积归一化法。所研制的没食子酸辛酯标准样品通过了均匀性检验和稳定性检验(6个月)。经定值检测,该标准样品的质量分数为99.472 0%,不确定度为0.03%。

| Abstract: | Preparation,homogeneity,stability and certification of reference material of octyl gallate were studied.Highly purified reference material of octyl gallate was prepared from an industrial grade product of octyl gallate by solvent re-crystallization in ethanol and water.The content of octyl gallate in reference material was measured by peak area normalization of high performance liquid chromatographic analysis method.The reference materials passed the tests of homogeneity and stability(6 months).The measured mass fraction of octyl gallate reference material was 99.472 0% with uncertainty of 0.03% by certification. |
