16 Facts About Mass spectrometry

Mass spectrometry is an analytical technique that is used to measure the mass-to-charge ratio of ions.

Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.

Mass spectrometry spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio.

Mass spectrometry accuracy is usually measured in ppm or milli mass units.

Mass spectrometry spectra are obtained by Fourier transformation of the recorded image currents.

All tandem mass spectrometry data comes from the experimental analysis of standards at multiple collision energies and in both positive and negative ionization modes.

Certain applications of mass spectrometry have developed monikers that although strictly speaking would seem to refer to a broad application, in practice have come instead to connote a specific or a limited number of instrument configurations.

An important enhancement to the mass resolving and mass determining capabilities of mass spectrometry is using it in tandem with chromatographic and other separation techniques.

Capillary electrophoresis–mass spectrometry is a technique that combines the liquid separation process of capillary electrophoresis with mass spectrometry.

Ion mobility spectrometry-mass spectrometry 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.

Tandem mass spectrometry purposely produces fragment ions post-source and can drastically change the sort of data achieved by an experiment.

Mass spectrometry is used to determine the isotopic composition of elements within a sample.

Mass spectrometry is an important method for the characterization and sequencing of proteins.

Mass spectrometry spectrometers are widely used in space missions to measure the composition of plasmas.

Mass spectrometry spectrometers were used in hospitals for respiratory gas analysis beginning around 1975 through the end of the century.

Primary function of mass spectrometry is as a tool for chemical analyses based on detection and quantification of ions according to their mass-to-charge ratio.
