## Abstract A novel approach for differentiation and dating of red ink entries of seals on documents was developed based on ionβpairing HPLC (IPβHPLC) and GC/MS. Sixtyβnine red ink pastes of seals were collected and the chromatographic conditions for separation of the dye components by IPβHPLC and
A laser desorption/ionization ion trap mass spectrometer was developed and used for the identification of polycyclic aromatic hydrocarbons (PAHs) and pesticides, DDT and BHC, condensed on a single microparticle. The excimer (XeCl, 308 nm) laser was adopted for the desorption and ionization of the ma
