Abstract
Ambient Mass Spectrometry (AMS) has revolutionized forensic analysis by enabling rapid and direct detection of chemical compounds on complex surfaces with minimal or no sample preparation. Among AMS techniques, desorption electrospray ionization (DESI) and direct analysis in real time (DART) mass spectrometry have emerged as powerful analytical tools due to their speed, sensitivity, and versatility. This review examines the major applications of DESI and DART in forensic science, including the detection of explosives, gunshot residue, illicit drugs, inks, biological fluids, and latent fingerprints. The principles of each technique are briefly discussed, followed by a comparative analysis of their advantages, limitations, and performances in various forensic scenarios. Recent developments, practical considerations for implementation, and future perspectives are also addressed, highlighting the growing impact of DESI and DART in real-time forensic investigations and evidence processing.
期刊介绍:
The Journal of the American Society for Mass Spectrometry presents research papers covering all aspects of mass spectrometry, incorporating coverage of fields of scientific inquiry in which mass spectrometry can play a role.
Comprehensive in scope, the journal publishes papers on both fundamentals and applications of mass spectrometry. Fundamental subjects include instrumentation principles, design, and demonstration, structures and chemical properties of gas-phase ions, studies of thermodynamic properties, ion spectroscopy, chemical kinetics, mechanisms of ionization, theories of ion fragmentation, cluster ions, and potential energy surfaces. In addition to full papers, the journal offers Communications, Application Notes, and Accounts and Perspectives
