A corona discharge initiated electrochemical electrospray ionization technique [PDF]
Journal of the American Society for Mass Spectrometry, 2009 We report here the development of a corona discharge (CD) initiated electrochemical (EC) electrospray ionization (ESI) technique using a standard electrospray ion source. This is a new ionization technique distinct from ESI, electrochemistry inherent to ESI, APCI, and techniques using hydroxyl radicals produced under atmospheric pressure conditions. By
