Electrospray may be used in nanotechnology, [18] for example to deposit single particles on surfaces. This is done by spraying colloids on average containing only one particle per droplet. The solvent evaporates, leaving an aerosol stream of single particles of the desired type.
Electrospray (nanoSpray) ionization source. 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.
Electrospray-assisted laser desorption/ionization (ELDI) uses a 337 nm UV laser [79] or 3 μm infrared laser [80] to desorb material into an electrospray source. Matrix-assisted laser desorption electrospray ionization (MALDESI) [81] is an atmospheric pressure ionization source for generation of multiply charged ions. An ultraviolet or infrared ...
Extractive electrospray ionization (EESI) [1] [2] is a spray-type, ambient ionization source [3] [4] [5] [6] [7] in mass spectrometry that uses two colliding aerosols ...
Nanospray desorption electrospray ionization (nano-DESI) is an ambient pressure ionization technique used in mass spectrometry (MS) for chemical analysis of organic molecules. [1] In this technique, analytes are desorbed into a liquid bridge formed between two capillaries and the sampling surface. [ 2 ]
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 ...
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 ...
ESTASI is a contactless process based on capacitive coupling. One advantage of ESTASI is, that the electrode and sample droplet act contact-less avoiding thereby any oxidation or reduction of the sample compounds at the electrode surface, which often happens during standard electrospray ionization (ESI).
