The substance to be analyzed is ejected from a 10 micrometer capillary, where it forms a Taylor cone.  
Both the charged residue model and the ion evaporation model are two competing theories that explain this technique, which has been used in colloid thrusters to control satellites, and to study noncovalent gas phase interactions, in addition to its best-known usage.  The substance to be analyzed is ejected from a 10 micrometer capillary, where it forms a Taylor cone.  Coulombic fission breaks up the resulting droplets, forming the target lone ions.  Used to isolate ions for mass spectroscopy, FTP, identify this technique that earned John B. Fenn a share of the 2002 Nobel Prize in chemistry.
