The dating of documents is crucial in forensic chemistry, particularly for verifying their authenticity. This study aimed to develop a rapid and direct method for the dating of pen ink in documents, using a combination of Fourier transform infrared spectroscopy in attenuated reflectance mode FTIR-ATRdesorption electrospray ionization mass spectrometry DESI-MS and multiple ensemble data modeling. Two sets of paper document samples containing writing in blue pen ink were investigated: I artificially aged documents and II real documents dating from to DESI-MS confirmed the presence of BV3 and its ink by-products in all the samples, indicating its widespread utilization in blue pen ink production.
These analyses proved to be effective for the dating of pen inks and are suitable for use in routine forensic analysis, providing a direct and rapid method that allows for accurate prediction.
