The electrospray ionization technique was first reported by Masamichi Yamashita and John Fenn in 1984, [3] and independently by Lidia Gall and co-workers in Soviet Union, also in 1984. [4] Gall's work was not recognised or translated in the western scientific literature until a translation was published in 2008. [4]
A close-up of an electrospray device, with emitter tip in foreground pointing to the right. The jet of ionised spray is visible within the image. To simplify the discussion, the following paragraphs will address the case of a positive electrospray with the high voltage applied to a metallic emitter.
Photograph of a meniscus of polyvinyl alcohol in aqueous solution showing a fibre drawn from a Taylor cone by the process of electrospinning. A Taylor cone refers to the cone observed in electrospinning, electrospraying and hydrodynamic spray processes from which a jet of charged particles emanates above a threshold voltage.
Desorption electrospray ionization (DESI) is an ambient ionization technique that can be coupled to mass spectrometry (MS) for chemical analysis of samples at atmospheric conditions. Coupled ionization sources-MS systems are popular in chemical analysis because the individual capabilities of various sources combined with different MS systems ...
If the molecular cohesion of the liquid is sufficiently high, stream breakup does not occur (if it does, droplets are electrosprayed) and a charged liquid jet is formed. [ 4 ] [ 5 ] As the jet dries in flight, the mode of current flow changes from ohmic to convective as the charge migrates to the surface of the fiber.
Secondary electrospray ionization mechanism diagram. In the early days of SESI, two ionization mechanisms were under debate.: the droplet-vapor interaction model postulates that vapors are adsorbed in the electrospray ionization (ESI) droplets, and then reemitted as the droplet shrinks, just as regular liquid phase analytes are produced in electrospray ionization; on the other hand, the ion ...

A colloid thruster (or "electrospray thruster") is a type of low thrust electric propulsion rocket engine that uses electrostatic acceleration of charged liquid droplets for propulsion. In a colloid thruster, charged liquid droplets are produced by an electrospray process and then accelerated by a static electric field.
