Forensic analysis of Toners by Thin Layer Chromatography and High Performance Thin Layer Chromatography

摘要

The counterfeiting of printed documents is most common phenomenon in the modern world. The aim of the present research is to examine suspected documents from their ink components. 28 raw and processed toners were analyzed for their colored ink components by thin layer chromatography and high performance thin layer chromatography. Chloroform was efficient to extract all dye components from the inks. The separation was performed using two separate mobile phases. It is possible to differentiate toner cartridges by TLC and HPTLC.
