Analytical Techniques for Trace Element Analysis: an Overview A.K.Ahuja 1

Abstract: Different novel analytical techniques have been used for the long time by the researchers for the determination of trace, major and minor elements particularly in coal fly ash, sand, water, nail polish, lipstics, chips and in plant samples. These include X-ray Florescence techniques like EDXRF & WDXRF, Atomic Absorption Spectroscopy, Neutron Activation Analysis, and Proton Induced X-ray Emission techniques. We have made an attempt to review these techniques, their sensitivity, suitability, minimum detection limits for their applicability to analysis of various samples
