摘要
目的建立电感耦合等离子体-质谱(ICP-MS)法检测中药材中铍、铬、锰、铜、砷、银、镉、锡、钡、镝、汞、铊、铅13种元素含量的方法。方法微波消解法制备供试品,全定量法采集数据。结果13种元素标准曲线线性关系良好,r=0.9993～1.0000,回收率符合痕量分析要求。结论本法灵敏度高,检测限低,分析速度快,分析精密度高。
OBJECTIVE To establish a method for the determination of 13 elements （Be, Cr, Mn, Cu, As, Ag, Cd, Sn, Ba, Dy, Hg,T1, Pb） in Chinese materia medica by inductively coupled plasma mass spectrometry （ICP-MS） .METHODS 13 elements of the digested samples were. determined by ICP-MS simultaneously, and the contents were calculated by calibration curves. RESULTS Good linearity of calibration curves was obtained for each ICP-MS assay, the accuracy and the recovery met the requirement of trace analysis. CONCLUSION The method is highly sensitive, rapid, accuracy and offered with low LOD.
