| 摘 要： | 研究了乙酸龙脑酯标准样品的制备、均匀性和稳定性及其定值方法。乙酸龙脑酯标准样品的制备采用高纯度天然龙脑的乙酰化法,乙酸龙脑酯标准样品的含量测定采用气相色谱面积归一化法,制备得到的乙酸龙脑酯标准样品通过了均匀性检验,且至少在24个月内是稳定的。乙酸龙脑酯标准样品的多实验室联合定值结果表示为:乙酸龙脑酯含量的标准值99.93%;标准不确定度0.08%;扩展不确定度(95%置信率)0.16%。

| Abstract: | Preparation,homogeneity,stability and certification of reference substance of bornyl acetate were studied.The reference substance of bornyl acetate was prepared by acetylation of highly pure borneol isolated and purified from a natural borneol product.The content of bornyl acetate in reference material was measured by gas chromatographic area normalization.The reference substance of bornyl acetate passed the test of homogeneity,and it was stable during 24 months at least.The joint certification results of bornyl acetate reference substance through multiple labs showed that the standard value of bornyl acetate content was 99.93 % with standard uncertainty of 0.08 %,extended uncertainty of 0.16 % and confidence coefficient of 95 %. |
