dc.description.abstract© 2021 American Society for Mass Spectrometry. Published by the American Chemical Society. All rights reserved.Documents with handwritten portions are often susceptible to adulteration, forgery, and addition of entries, raising a problem of social concern. In this study, DESI ionization with imaging capabilities is applied to identify fraud in handwritten documents made using erasable pens of the chemical method of erasing (other than the usual physical methods). A fraud procedure was simulated in which an original entry made in white office paper was erased and replaced with a new one. The areas were directly analyzed using a DESI-MSI ion source coupled to a Q-Extractive mass spectrometer. Chemical images were obtained mapping the intensity of selected ions, spelling out each part of the fraud process as irrefutable evidence of its occurrence. Thus, the potential application of DESI-MSI in detecting fraud in suspect documents is demonstrated as a useful, simple, and fast alternative for the traditional techniques employed in these situations.
