Abstract

Objective: The present study was designed to perform the analysis of ballpoint pen inks of different brands. Methods: The ballpoint pen inks components were separated by TLC and then separated components were analyzed by means of Ultraviolet visible (UV-Vis), infrared (IR) and NMR spectroscopy. Results: UV-Vis analysis was successful in characterizing ballpoint pen inks of different brands. IR analysis revealed that each brands could be characterized and then differentiated by looking the pattern of each spectra. NMR spectroscopy has been useful for the comparison of ink brands. Conclusion: The present findings indicate that by the above used analytical techniques the forgery of documents can be caught.

Keywords: Ballpoint Pen, TLC, UV-VIS, IR, NMR spectroscopy.
