摘 要:目的:采用HPLC—NQAD(水凝聚核粒子计数蒸发光检测器)法和HPLC—ELSD(中国药典方法)法测定硫酸卡那霉素注射液的含量,并对2种方法进行比较。方法:采用AgilentSBC18色谱柱(250mm×4.6mm,5μm),流动相为0.2%三氟乙酸溶液-甲醇(80:20,V/V)。结果:卡那霉素进样量在195.2~1952ng范围内具有良好的线性,相关系数为0.9991,卡那霉素检出限为19.4ng,卡那霉素样品的加样回收率为99.7%(n=9)。结论:本方法具有较高的准确度、精密度和灵敏度,方法简便,可用于卡那霉素的检测分析。该方法较药典方法有较高的灵敏度,且峰面积与浓度直接线性响应。Objective:To determine the content of kanamycin sulfate injection by methods of HPLC -NQAD( nano quantity analyte detector)and HPLC -ELSD (evaporative light scattering detector, the method as described in the Chinese pharmacopoeia) and compare the two methods. Methods: The chromatographic separation was achieved with Agilent SB C18 column ( 250 mmx 4. 6 ram, 5μm) by 0. 2% trifluoroacetic acid - methanol ( 80: 20, V/V). Results: The calibration curve of kanamycin was linear in the range of 195.2 -1952 ng( r =0. 9991 ) ,the detection limit of kanamycin was 19.4 ng,the average recovery was 99.7%. Conclusion:The method established is accurate, sensi- tive, and reliable for the determination of kanamycin sulfate injection. The method has higher sensitivity compared with the pharmacopoeia method, and the peak area has a direct response with concentration.
