  2. Electrospray ionization - Wikipedia

    en.wikipedia.org/wiki/Electrospray_ionization

    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]

  3. Electrospray - Wikipedia

    en.wikipedia.org/wiki/Electrospray

    In 1914, John Zeleny published work on the behaviour of fluid droplets at the end of glass capillaries. [5] This report presents experimental evidence for several electrospray operating regimes (dripping, burst, pulsating, and cone-jet). [6] A few years later, Zeleny captured the first time-lapse images of the dynamic liquid meniscus. [7]

  4. Colloid thruster - Wikipedia

    en.wikipedia.org/wiki/Colloid_thruster

    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.

  5. Sample preparation in mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation_in_mass...

    Electrospray ionization (ESI) is a technique that involves using high voltages to create an electrospray, or a fine aerosol created by the high voltages. [31] ESI sample preparation can be very important and the quality of results can be heavily determined by the characteristics of the sample. [32] ESI experiments can be run on-line or off-line.

  6. Liquid metal ion source - Wikipedia

    en.wikipedia.org/wiki/Liquid_metal_ion_source

    A liquid metal ion source (LMIS) is an ion source which uses metal that is heated to the liquid state and used to form an electrospray to form ions. [1] [2] An electrospray Taylor cone is formed by the application of a strong electric field and ions are produced by field evaporation at the sharp tip of the cone, which has a high electric field.

  7. Desorption electrospray ionization - Wikipedia

    en.wikipedia.org/wiki/Desorption_electrospray...

    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 ...

  8. Ion source - Wikipedia

    en.wikipedia.org/wiki/Ion_source

    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 ...

  9. Taylor cone - Wikipedia

    en.wikipedia.org/wiki/Taylor_cone

    This cone was described by Sir Geoffrey Ingram Taylor in 1964 before electrospray was "discovered". [1] This work followed on the work of Zeleny [2] who photographed a cone-jet of glycerine in a strong electric field and the work of several others: Wilson and Taylor (1925), [3] Nolan (1926) [4] and Macky (1931).
