An ion source is a device that creates atomic and molecular ions. Ion sources are used to form ions for mass spectrometers, optical emission spectrometers, particle accelerators, ion implanters and ion engines. Meer weergeven Electron ionization is widely used in mass spectrometry, particularly for organic molecules. The gas phase reaction producing electron ionization is where M is the atom or molecule being ionized, is … Meer weergeven Photoionization is the ionization process in which an ion is formed from the interaction of a photon with an atom or molecule. Multi-photon … Meer weergeven Spray ionization methods involve the formation of aerosol particles from a liquid solution and the formation of bare ions after solvent evaporation. Solvent … Meer weergeven Chemical ionization (CI) is a lower energy process than electron ionization because it involves ion/molecule reactions rather than electron removal. The lower energy yields less Meer weergeven These ion sources use a plasma source or electric discharge to create ions. Inductively-coupled plasma Ions can be created in an inductively coupled plasma Meer weergeven Field desorption Field desorption refers to an ion source in which a high-potential electric field is applied to an emitter with a sharp surface, such as a razor blade, or more commonly, a filament from which tiny "whiskers" have formed. This … Meer weergeven Thermal ionization (also known as surface ionization, or contact ionization) involves spraying vaporized, neutral atoms onto a hot surface, from which the atoms re-evaporate in ionic form.
