Some Thoughts on Electrospray Ionization Mechanisms
European Journal of Mass Spectrometry, 2011 Electrospray ionization (ESI) mechanisms are highly complex, due to a series of physical and chemical phenomena taking place on a complex system, as a solution is. In fact, even if the solution of an analyte in a protic medium can be considered at first sight to be a two-component system, the presence of solvent dissociation ...
