| Abstract: | OBJECTIVE To establish a method for the determination of 13 elements (Be, Cr, Mn, Cu, As, Ag, Cd, Sn, Ba, Dy, Hg, Tl, 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. |
