There are two major theories that explain the final production of gas-phase ions: the ion evaporation model (IEM) and the charge residue model (CRM). The IEM suggests that as the droplet reaches a certain radius the field strength at the surface of the droplet becomes large enough to assist the field … See more Electrospray ionization (ESI) is a technique used in mass spectrometry to produce ions using an electrospray in which a high voltage is applied to a liquid to create an aerosol. It is especially useful in producing ions from See more The electrosprays operated at low flow rates generate much smaller initial droplets, which ensure improved ionization efficiency. … See more • Probe electrospray ionization • Laser ablation electrospray ionization • Sonic spray ionization See more • Cole, Richard (1997).
