Abstract
Multielement analysis was carried out in two samples of natural rubies obtained from Kenya and Tanzania and a synthetic ruby obtained locall y. The trace element profile was used to characterise the ruby samples . Instrumental Neutron Activation Analysis (INAA) by the single compar ator (K-0 method) was used to determine the concentrations of 22 eleme nts with gold as the comparator. High resolution gamma-ray spectrometr y was employed for radiometric assay of the activation products. The a ccuracy and precision were evaluated by analysing standard reference m aterials such as USGS-W-1 and AGV-1 and were found to be satisfactory.
