Ionization source

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.
