| Abstract: | The identification of relative age of the ink entries written by the same black signing-pen on documents stored in different light conditions is presented. The documents were stored in darkness and exposed to daylight and artificial light from 500 W visible analyzer for quite a number of days, respectively. Inks were then extracted from the respective documents and analyzed by HPLC. The variations of the relative contents of the dye component in the ink extracted from the documents under different light conditions were further studied. The variation regularities of the dye component under different aging conditions thus obtained would be the basis for the identification of the aging time of the ink entries written by the black signing-pen on documents. |
