摘要
建立了顶空-气相色谱法检测琥珀酸美托洛尔中残留溶剂(丙酮和异丙醇)的测定方法.被测样品的各个组分在非极性弹性石英毛细管柱上能有效分离;在0.001~0.300 mg/mL浓度范围内,线性相关系数R≥0.9990;加标回收率为90.73%~104.80%,相对标准偏差为0.76%~11.85%( n=5),方法的检出限为2.00μg/mL.该方法检测琥珀酸美托洛尔中的残留溶剂重现性好,定量准确,便于操作.
A method is set up which detects residual solvents that remains in metroprolol succinate by headspace chromatogra-phy.External reference method and headspace auto-sample injection is used through nonpolarity flexibility quartz capillary chromato-graphic column and get a good effect.The linear range is from 0.001 to 0.300 mg/mL, the correlation coefficient R≥0.9990;stand-ard solution spiked levels from 0.001 to 0.300 mg/mL, the recovery rate is 90.73%to 104.80%, and the relative standard deviation is from 0.76%to 11.85%, the detection limit of method is 1.00μg/mL.This method of determining metroprolol succinate has a good reproducibility,nice quantitative and the operation is very easy.
