Differentiation of Blue Ballpoint Pen Inks by Laser Desorption Ionization Mass Spectrometry and High-Performance Thin-Layer Chromatography

The differentiation of inks on a questioned document can highlight a fraudulent insertion and is usually carried out by optical comparison and thin‐layer chromatography (TLC). Laser desorption ionization mass spectrometry (LDI‐MS) may also be used for the analysis of dyes from ink. This analytical t...
