The landscape of analytical chemistry has undergone a profound transformation over the last two decades. Traditionally, mass spectrometry (MS)—the "gold standard" for chemical identification—was a laboratory-bound technique requiring extensive sample preparation and high-vacuum environments. However, the advent of Desorption Electrospray Ionization (DESI) and the subsequent development of portable mass spectrometer "dose" or delivery systems have liberated chemical analysis from the lab. By allowing for real-time, ambient ionization, these portable systems are revolutionizing fields ranging from surgical oncology to forensic science and environmental monitoring.
