Abstract | The aim of the project was to evaluate the discriminating power of various methods used to differentiate ballpoint pen inks, including optical methods, Raman spectrometry and the TLC method. The work focused on how to develop the most effective procedure to ensure quality when thin layer chromatography is used to differentiate writing materials. An essential element of this procedure was finding appropriate extracting solvent – developing solvent systems that would ensure a well-differentiated chromatogram. 16 blue ballpoint pen inks produced by the four most popular Polish firms were used as research material. |
