目的:建立电感耦合等离子体原子发射光谱法(ICP-AES)和电感耦合等离子体质谱法(ICP-MS)测定脂肪乳类注射液中铝元素杂质含量的方法,并比较两者的差异。方法:通过方法学验证及样品的测定,对2种方法的线性、准确度、重复性、检测限、定量限和测定结果进行对比分析。结果:2种方法的铝离子浓度在5~200μg。L-1范围内呈良好的线性关系,相关系数均大于0。999,加样回收率平均值分别为103。0%、106。7%、103。2%(n=9)和99。8%、106。5%、100。8%(n=9);重复性试验结果 RSD 均为 2。0%(n=9),方法检出限分别为1。22和0。36 µg·L-1,方法定量限分别为4。07和1。20 µg·L-1,8批脂肪乳类注射液样品的铝元素杂质测定结果基本一致。结论:上述两种方法操作简单、灵敏,准确度高、重现性好,均可用于脂肪乳类注射液中铝元素杂质的含量测定。
Determination of aluminum in fat emulsion injection by ICP-AES and ICP-MS
Objective:To establish ICP-AES and ICP-MS methods for determination of aluminum impurities in fat emulsion injection and compare the difference between the two methods.Methods:Compare the linearity,accura-cy,repeatability,detection limit,quantification limit and sample determination results of the two methods by meth-odological verification and determination.Results:The linearity range of two methods were 5-200 μg·L-1,the correlation coefficients were greater than 0.999,the average recovery were 103.0%,106.7%,103.2%(n=9)and 99.8%,106.5%,100.8%(n=9),The RSD of reproducibility both were 2.0%,the detection limit of two methods were 1.22 and 0.36 μg·L-1.The quantification limit of two methods were 4.07 and 1.20 μg·L-1.The contents of aluminum impurities in 8 batches of fat emulsion injection were basically the same.Conclusion:The two methods were convenient,sensitive,accurate and good repeatability,which can be used for the determination of aluminum impurities in fat emulsion injection.
