Dear Sir. Concerning your issue about the characterization of metal containing compounds by ICP technique . Analytical chemistry of metal complexes with biomacromolecules based on the coupling of a high resolution separation technique with an element or species selective detection technique. Inductively coupled plasma atomic emission spectrometry (ICP AES) and ICP mass spectrometry (ICP MS) are used for the characterization of metal containing compounds. I think the following below links may help you in your analysis:

Thanks

ICP-MS and ICP-AES could determined the trace and ultra trace level impurities in high purity metals.
