Mass spectrometry
Mass spectrometry using electric and magnetic fields measures mass-to-charge ratio of molecules. Several ionization methods like electron impact, chemical ionization, electrospray, fast atom bombardment, matrix assisted laser desorption ionization, and others are involved in Mass Spectrometry. Mass spectrometry is also categorized by approaches of mass analyzers like magnetic-sector, quadrupole mass analyzer, quadrupole ion trap, time-of-flight, Fourier transform ion cyclotron resonance, and many other types are involved in Mass Spectrometry.In order to measure the characteristics of individual molecules, a mass spectrometer converts them to ions so that they can be moved about and manipulated by external electric and magnetic fields.
