This web page might be of interest for you, if you haven't seen it yet - Ink
chemistry<http://www.rsc.org/chemistryworld/Issues/2003/March/inkchemistry.asp>
And so is the following article - "Investigation of ball point pen inks by
capillary electrophoresis (CE) with UV/Vis absorbance and laser induced
fluorescence detection and particle induced x-ray emission
(PIXE)<http://library-resources.cqu.edu.au/JFS/PDF/vol_44/iss_4/JFS4440819.pdf>
