Mass Analyzers and Mass Spectrometers
2016Mass spectrometers are comprised of three main components: an ion source, a mass analyzer, and a detector. Ionization of the analyte occurs in the ion source and the resulting ions are counted at the detector. However, it is the mass analyzer that is responsible for determing the mass-to-charge ratio (m/z) of the ions (Jennings KR, Dolnikowski GG ...

An atmospheric-pressure ionization mass spectrometer/mass spectrometer
International Journal of Mass Spectrometry and Ion Physics, 1983Abstract This report gives data about the construction and performance of an atmospheric-pressure ionization source which provides positive or negative ions for a tandem mass spectrometer. The ions can be mass-analyzed in one or both of two Balzer quadrupole mass-analyzers.

High-Resolution Mass Spectrometers
Annual Review of Analytical Chemistry, 2008Over the past decade, mass spectrometry has been revolutionized by access to instruments of increasingly high mass-resolving power. For small molecules up to ∼400 Da (e.g., drugs, metabolites, and various natural organic mixtures ranging from foods to petroleum), it is possible to determine elemental compositions (CcHhNnOoSsPp…) of thousands of ...

A mass spectrometer mass marker
Journal of Scientific Instruments, 1958An instrument has been constructed which utilizes the galvano-magnetic effect in bismuth to measure the field strength of a mass spectrometer magnet, and hence to determine the masses of peaks as they occur when the spectrum is scanned by variation of the magnetic field strength at constant accelerating voltage.
