Abstract
The impetus for the refinement and renewal of daily-used products has spurred international
interest in investigating the small in homogeneities that might exist in these products. This interest
has become an important part in the design philosophy, which is based on structural information
gained by the analysis of these products.
It is this drive that initiated the study to investigate the simultaneous use of novel nuclear analytical
techniques such as micro proton induced X-ray emission( u-PlXE), micro proton induced
gamma-ray emission (u-PlGE) and micro proton backscattering (u-RBS) to achieved a
broader and yet deeper insight into the fine structure of products. The fundamental underlying
physical principles of these techniques are discussed to gain in-depth knowledge on how to
them to obtain the desired information. Also determined was the degree of accuracy that could
be attained in the application of this knowledge. These principles were evaluated in conjunction
with the instrumentation with which the applicability of these techniques could then be
further extended. More so is the use of sophisticated software that facilitated the use of both
physical and instrumental parameters. After describing the necessary implements to achieve
this further know-how, products of industrial origin were investigated to determine in homogeneities
that existed in those products and compared those theoretical values.
The first application was made to ceramic-based sorption electrodes to be used in the purification
of wastewater.
