Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.
MASS decoy launcher of a Hamina-class missile boat.. Multi Ammunition Softkill System (MASS) is a naval self-defence system produced by Rheinmetall of Germany.It is connected to the ship's sensors and protects ships from attacks by advanced sensor-guided missiles by launching decoys that operate in all relevant wavelengths of the electromagnetic spectrum: ultraviolet, electro-optical, laser ...
Atmospheric pressure photoionization (APPI) is a soft ionization method used in mass spectrometry (MS) usually coupled to liquid chromatography (LC). Molecules are ionized using a vacuum ultraviolet (VUV) light source operating at atmospheric pressure (105 Pa), either by direct absorption followed by electron ejection or through ionization of a ...
ESI is a so-called 'soft ionization' technique, since there is very little fragmentation. This can be advantageous in the sense that the molecular ion (or more accurately a pseudo molecular ion) is almost always observed, however very little structural information can be gained from the simple mass spectrum obtained.
Soft Ionization by Chemical Reaction in Transfer is a method for ionizing small organic ... The separated cell is introduced into the mass spectrometer through the ...
Chemical ionization (CI) is a soft ionization technique used in mass spectrometry. [1] [2] This was first introduced by Burnaby Munson and Frank H. Field in 1966. [3] This technique is a branch of gaseous ion-molecule chemistry. [2]
Ion-attachment mass spectrometry (IAMS) is a form of mass spectrometry that uses a "soft" form of ionization similar to chemical ionization in which a cation is attached to the analyte molecule in a reactive collision:
Koichi Tanaka performed the first successful LDI experiments on proteins. [1] Subsequently, Sunner and Chen used graphite particles of 2-150 μm in size as a substrate and solutions of analytes in glycerol to analyze low molecular weight analytes, peptides, and small proteins by surface-assisted laser desorption/ionization MS (SALDI-MS).
