Variants

IonizationType

ionization type - The method by which gas phase ions are generated from the sample.

AtmosphericPressureChemicalIonization

atmospheric pressure chemical ionization - Chemical ionization that takes place at atmospheric pressure as opposed to the reduced pressure is normally used for chemical ionization.

ChemicalIonization

chemical ionization - The formation of a new ion by the reaction of a neutral species with an ion. The process may involve transfer of an electron, a proton or other charged species between the reactants. When a positive ion results from chemical ionization the term may be used without qualification. When a negative ion results the term negative ion chemical ionization should be used. Note that this term is not synonymous with chemi-ionization.

ElectrosprayIonization

electrospray ionization - A process in which ionized species in the gas phase are produced from an analyte-containing solution via highly charged fine droplets, by means of spraying the solution from a narrow-bore needle tip at atmospheric pressure in the presence of a high electric field. When a pressurized gas is used to aid in the formation of a stable spray, the term pneumatically assisted electrospray ionization is used. The term ion spray is not recommended.

FastAtomBombardmentIonization

Autoionization

autoionization - The formation of an ion when an atom or molecule in a discrete state with an energy greater than the ionization threshold loses an electron spontaneously without further interaction with an energy source.

Nanoelectrospray

nanoelectrospray - Electrospray ionization at a flow rate less than ~25 nL/min. Nanoelectrospray is synonymous with nanospray. The flow is dependent on the potential on the tip of the electrospray needle and/or a gas pressure to push the sample through the needle. See also electrospray ionization and microelectrospray.

PenningIonization

penning ionization - Ionization that occurs through the interaction of two or more neutral gaseous species, at least one of which is internally excited.

ProtonTransferChargeReduction

proton transfer charge reduction - Process to transfer one or more protons from a multiply charged cation (peptide or protein ion) to a proton acceptor anion or neutral basic compound, thereby reducing the charge of the original analyte.

SecondaryElectrosprayIonization

secondary electrospray ionization - Secondary electrospray ionization (SESI) is an atmospheric pressure ionization (API) technique that uses a primary nano-electrospray plume of solvent ions to ionize neutral gaseous molecules in the gas phase via efficient proton transfer reactions. Operating at atmospheric pressure, SESI allows for the sensitive and real-time detection of volatile organic compounds (VOCs) and vapors with minimal sample preparation, making it ideal for applications like breath analysis and environmental monitoring.

ArgonGasClusterIonBeam

argon gas cluster ion beam - Argon gas cluster ion beam (Ar GCIB) bombardment uses a focused beam of large argon cluster ions, typically [Ar500]+ to [Ar10000]+, accelerated to high energies to sputter and generate secondary ions from a surface, enabling molecular depth profiling and imaging of organic and biological materials with reduced subsurface damage compared to monatomic ion beams.

BismuthLiquidMetalIonGun

bismuth liquid metal ion gun - Bismuth liquid metal ion gun (Bi LMIG) bombardment uses a focused beam of bismuth ions emitted from a liquid metal ion source to desorb and ionize molecules from a surface. The LMIG source generates a diversity of monomers and clusters, which are filtered prior to the sample in order to select the specific ionisation characteristics.

GasClusterIonBeam

gas cluster ion beam - A gas cluster ion beam (GCIB) is an ion source that generates and accelerates large aggregates of gas atoms or molecules to high energies. The low energy per constituent atom minimizes surface damage and molecular fragmentation, making it highly effective for molecular depth profiling and the analysis of fragile organic and biological materials.

LiquidMetalIonGun

liquid metal ion gun - A liquid metal ion gun (LMIG) is an ion source that extracts and ionizes a thin layer of liquid metal from a fine heated needle using a high-voltage electric field. It produces a high-brightness, tightly focused beam of metal ions or clusters, enabling high-resolution imaging and analysis in Secondary Ion Mass Spectrometry (SIMS).
