  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. 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 ...

  5. Electrostatic spray ionization - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_spray_ionization

    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). [2]

  6. Extractive electrospray ionization - Wikipedia

    en.wikipedia.org/wiki/Extractive_electrospray...

    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 ...

  7. Ion trap - Wikipedia

    en.wikipedia.org/wiki/Ion_trap

    Schematic diagram of ion trap mass spectrometer with an electrospray ionization (ESI) source and Paul ion trap. A Paul trap is a type of quadrupole ion trap that uses static direct current (DC) and radio frequency (RF) oscillating electric fields to trap ions. Paul traps are commonly used as components of a mass spectrometer.

  8. Direct analysis in real time - Wikipedia

    en.wikipedia.org/wiki/Direct_analysis_in_real_time

    In mass spectrometry, direct analysis in real time (DART) is an ion source that produces electronically or vibronically excited-state species from gases such as helium, argon, or nitrogen that ionize atmospheric molecules or dopant molecules.

  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).
