Mass spectrometry is a type of chemical analysis that measures the mass of ions, and calculates the relative abundance of each of those ions within the sample. It’s a kind of instrumental analysis, which means the sample is processed and measured within a device, or instrument, called a mass spectrometer. A sample ... Basic Principles. At its core, mass cytometry is a fusion of two experimental platforms: flow cytometry and elemental mass spectrometry (Fig. 1).The current instrumentation for mass cytometry is called Cytometry by Time-Of-Flight (CyTOF) and is described in detail elsewhere (Bandura et al., 2009; Bjornson et al., 2013), but we …A mass spectrometer can measure the mass of a molecule only after it converts the molecule to a gas-phase ion. To do so, it imparts an electrical charge to molecules and converts the resultant flux of electrically charged ions into a proportional electrical current that a data system then reads. The data system converts the current to digital ...MALDI-TOF Mass Spectrometry. Mass spectrometry is an analytical technique in which samples are ionized into charged molecules and ratio of their mass-to-charge (m/z) can be measured. In MALDI-TOF mass spectrometry, the ion source is matrix-assisted laser desorption/ionization (MALDI), and the mass analyzer is time-of-flight (TOF) analyzer..
