THIN LAYER CHROMATOGRAPHY OF INKS- A FORENSIC APPROACH

Bhavana. Desai, J. L. Kalyana

DOI : 10.9780/22307850, By : Laxmi Book Publication

Abstract :

Thin Layer Chromatography is a very effective tool for examination of ink since beginning. It has proved to be the most convenient methods in separation of inks. Ink is a liquid or a viscous pigmented substance used for writing, printing, and drawing. Ink’s composition and its consistency vary accordingly. It depends on the purpose for which it is used. However every ink is composed of components such as pigment or dye called colorant and vehicle. Some of the common types of inks are writing inks, printing inks, drawing inks, visible inks, and invisible or symphetatic inks. If the ink is exposed to certain liquids such as solvents the colour of the ink dissolves and gets separated. If the solution is allowed to soak on to the chromatogram different colour will separate into different spots on the plate according to their respective Rf values. In the present study THIN LAYER CHROMATOGRAPHY (TLC) has been applied to different types of inks to individualize them on the basis of their Retention Factor (Rf) which in turn helps the Forensic Expert to understand about the different inks used on the forged document. Thus by comparing the Rf values of these inks with the Rf values of the Questioned ink samples we can easily get an idea about the inks used in the preparation of a Questioned Document.
