Ion Suppression: A Major Concern in Mass Spectrometry

Web10 jun. 2024 · Within the mass spectrometer, the neutral molecules are first ionized, most commonly by electron ionization (EI). In EI, an electron, produced by a filament, is accelerated with 70 electron volts (eV) and knocks an electron out of the molecule to produce a molecular ion that is a radical cation.
