Ink analysis is the most challenging and commonly encountered problem faced
by a forensic chemist. Ink present on documents such as contracts, cheques,
testaments, medical records, to quote just a few, is regularly contested for its
authentication. In this paper, we have examined the various inks available in
Ethiopia (speciallyArba Minch) using chromatography and spectroscopy
methods, and have tried to decode the chemical compositions of these inks
emphasizing on coloring agents followed by evaluating the discrimination
potential of these techniques. This study is the first kind of detailed examination
of inks available in Ethiopia as there is no precedence literature to it. It was
found out that the examined ink samples can be divided into five major groups
having mainly rhodamine b, rhodamine 6G and crystal violet as coloring agents.
The TLC and UV-Vis techniques although discriminate inks samples to a little
better extent than VSC, but VSC should be preferred due to its non-destructive
nature.
