The effect of electrospray solvent composition on desorption electrospray ionisation (DESI) efficiency and spatial resolution
In desorption electrospray ionisation (DESI) the interaction between the electrospray and the surface is key to two important analytical parameters, the spatial resolution and the sensitivity. This paper evaluates the effect of the electrospray solvent type, organic solvent fraction with water, analyte solubility and substrate wettability on DESI erosion diameter and material transferral into useful ion signal.
