A:Recent advances in ambient electrospray ionization technologies [PDF]

Records of Pharmaceutical & Biomedical Sciences, 2020
Mass spectrometry is one of the most powerful techniques for detection and identification. Due to its sensitivity and selectivity, exact mass of analytes, and in effect, their relative fragments, allow for total structure information.

Enhanced desorption ionization using oxidizing electrosprays [PDF]

Journal of the American Society for Mass Spectrometry, 2006
A signal enhancement of two orders of magnitude was achieved when reactive desorption electrospray ionization (DESI) was used to investigate copper(II) dibutyl dithiocarbamate, Cu(II)(bu2dtc)2, found in a specialized polymer. Cu(II) was oxidized to Cu(III) during the DESI experiment by oxidants in the spray solvent.
