Role of analytical techniques for characterisation of advanced and high purity materials

High purity metals and other advanced materials are extensively employed in various applications connected with electronics, solar energy conversion, superconductors, shape memory alloys and other industrial applications of importance. In many of these applications, the properties are affected by the nature and concentration of impurities present in the material. The use of modern analytical techniques for chemical and surface characterization is highly beneficial for the evaluation of such materials for various critical applications. The sophisticated chemical analysis techniques like AAS, GFAAS, ICPAES, ICPMS, NAA and DPASV helps in chemical characterization which together with surface analytical techniques like XPS provides complete evaluation of the material for various applications.
