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 ...
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]
MS/MS – Mass spectrometry/mass spectrometry, i.e. tandem mass spectrometry MALDESI – Matrix-assisted laser desorption electrospray ionization MALDI – Matrix-assisted laser desorption/ionization
Ion mobility spectrometry-mass spectrometry (IMS/MS or IMMS) is a technique where ions are first separated by drift time through some neutral gas under an applied electrical potential gradient before being introduced into a mass spectrometer. [43] Drift time is a measure of the collisional cross section relative to the charge of the ion.
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).
Schematic of a quadrupole time-of-flight (QTOF) mass spectrometer. The different m/z separation elements of a hybrid mass spectrometer can be represented by a shorthand notation. The symbol Q represents a quadrupole mass analyzer , q is a radio frequency collision quadrupole, TOF is a time-of-flight mass spectrometer , B is a magnetic sector ...
Matrix-assisted laser desorption electrospray ionization (MALDESI) was first introduced in 2006 as a novel ambient ionization technique which combines the benefits of electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). [1]
