Analysis of amikacin sulfate injection by liquid chromatography with pulsed amperometric detection(液相色谱-脉冲安培电化学法测定硫酸阿米卡星注射液中主要组分和杂质)
建立了一种新的用反相离子对液相色谱(LC)分离、以金电极为工作电极的脉冲安培电化学法(PAD)直接检测硫酸阿米卡星注射液中主要组分及杂质含量的分析方法.流动相为0.033 mol • L-1草酸、0.012 mol • L-1七氟丁酸、108 ml • L-1乙腈,用稀NaOH调节pH至3.4.考察了各色谱参数对分离测定的影响.实验证明,该方法不需要衍生化,可直接检测硫酸阿米卡星.与报道的其他方法相比,该方法不仅能使硫酸阿米卡星注射液中的主要组分阿米卡星和杂质组分卡那霉素A得到了很好的分离,还分离出了其它一些未能确证的组分.可望今后用质谱法等对未知组分进行确证后,对硫酸阿米卡星原料药、注射液等...
