摘要
借助ICP-MS,建立了一种简单、快速的阿奇霉素铂含量的分析方法。在0.1~20μg/L浓度范围内,铂含量的响应值与其对应浓度呈线性关系,其相关系数为0.9999;方法检测限和定量限分别为0.0048 mg/kg和0.016 mg/kg;加标回收实验显示,在(0.1μg/L、6μg/L、20μg/L)3种浓度水平下,各回收率均大于70%,符合分析测试要求。
A simple and rapid method was established for the analysis of azithromycin platinum content by ICP-MS. In the range of 0.1-20 μg/L, the response of platinum content was linear with the corresponding concentration, and also the correlation coefficient was 0.9999; The method detection limit and quantitafion limit were 0.0048 mg/kg and 0.016 mg/kg, respectively; Spike recovery experiment showed that the recovery rate was more than 70 % when the concentration were 0.1 μg/L, 6 μg/L and 20 μg/L, respectively, which meet the analysis and testing requirements.
