The relative dating of the entries was performed by the quantification of the ballpoint pen ink dyes and their degradation products using HPLC . Results show that it is possible to determine the relative age of entries written by ballpoint pen within a relatively short time scale, if storage and supporting material of the different samples are the same or at least similar .
The current work is focused on the study of the dating of ink samples by using spectrophotometry technique and multiple regression analysis . A multiple linear regression (MLR) model has been proposed for the estimation of blue ballpoint pen ink dating by measuring the fading of ink with respect to time using UV-Vis spectrophotometer .

The dating of the documents written by ballpoint pens can be determined by variations of the volatile components in the inks , such as 2-phenoxyethanol [9][10][11], and changes of the ballpoint pen . . .

The aim of this work was to develop an ink dating methodology (DATINK) for documents written by ballpoint pens based on the disappearance of volatile solvents from the ink entry . Multiple solid-phase microextraction (MHS-SPME) coupled to GC/MS was used to measure the solvents from ink entries made with four BIC(®) ballpoint pens .
Ballpoint pen ink dating . The date on which an ink is entered on paper could be calculated if it were possible to track the behaviour of one or more of its components over time . In this way, lines of Blue and Black BIC ® ballpoint pens were drawn for a period of 5 years . The volatiles being considered in this paper were as follows: HG, benzaldehyde (BZ), phenol (Ph), benzyl alcohol (BA), and PE .
Ink dating may be performed on ballpoint pen inks . Currently, it is estimated that approximately 85% of ballpoint pen inks are manufactured using a chemical component known as, 2-phenoxyethanol or PE .
Abstract: The ink of pens and ink extracted from lines on white photocopier paper of 10 blue ballpoint pens were subjected to ultraviolet-visible (UV-Vis) spectroscopy, infrared (IR), and high‐performance thin‐layer liquid chromatography (HPTLC) . The Rf values and color tones of the bands separated by thin‐layer chromatography (TLC) analysis used . . .
