MALDI TOF mass spectrometer. In mass spectrometry, matrix-assisted laser desorption/ionization (MALDI) is an ionization technique that uses a laser energy-absorbing matrix to create ions from large molecules with minimal fragmentation. [1]
A Bradbury–Nielsen shutter is a type of ion gate used in TOF mass spectrometers and in ion mobility spectrometers, as well as Hadamard transform TOF mass spectrometers. [9] The Bradbury–Nielsen shutter is ideal for fast timed ion selector (TIS)—a device used for isolating ions over narrow mass range in tandem (TOF/TOF) MALDI mass ...
Laboratory information management software for mass spectrometry information management and data analysis. OpenChrom: Open source: Chromatography and mass spectrometry software that can be extended using plug-ins and can run on several operating systems (Microsoft Windows, Linux, Unix, Mac OS X) and processor architectures (x86, x86_64, ppc).
MALDI mass spectrometry imaging (MALDI-MSI) is the use of matrix-assisted laser desorption ionization as a mass spectrometry imaging [2] technique in which the sample, often a thin tissue section, is moved in two dimensions while the mass spectrum is recorded. [3]
Mass spectrometry (MS) is an ... One example is MALDI-TOF, ... Usually the first strategy for identifying an unknown compound is to compare its experimental mass ...
While the first generation of MALDESI system was coupled to Fourier transform (FT) ion cyclotron resonance mass spectrometer, [3] the current source is interfaced with a Thermo Exploris 240 or a Q Exactive Plus mass spectrometer equipped with an Orbitrap mass analyzer. These mass analyzers offer equally accurate mass measurements but generally ...
MS 2 – Mass spectrometry/mass spectrometry, i.e. tandem mass spectrometry; MS/MS – Mass spectrometry/mass spectrometry, i.e. tandem mass spectrometry; MALDESI – Matrix-assisted laser desorption electrospray ionization; MALDI – Matrix-assisted laser desorption/ionization; MAII – Matrix-assisted inlet ionization; MAIV – Matrix ...
In mass spectrometry, a matrix is a compound that promotes the formation of ions. Matrix compounds are used in matrix-assisted laser desorption/ionization (MALDI), matrix-assisted ionization (MAI), and fast atom bombardment (FAB).
