Mass to charge ratio meaning
The mass-to-charge ratio (m/Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics. It appears … Ver más When charged particles move in electric and magnetic fields the following two laws apply: • Lorentz force law: F = Q ( E + v × B ) , {\displaystyle \mathbf {F} =Q(\mathbf {E} +\mathbf {v} \times … Ver más In the 19th century, the mass-to-charge ratios of some ions were measured by electrochemical methods.

WebA mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio (m/z) of its ion. Ions are generated by inducing either the loss or gain of a charge from a neutral species. Once formed, ions are electrostatically directed into a mass analyzer where they are separated according to m/zand finally detected.
