WebMass spectrometry is an analytical technique used to identify and quantify chemical compounds based on their mass-to-charge ratio (m/z) and the abundance of the ions generated from the sample. Electron-impact ionization (EI) and chemical ionization (CI) are two common ionization sources used in mass spectrometry to generate ions from … WebIonization is effected by shooting energetic electrons onto a neutral that must have been transferred into the gas phase before. EI definitely is the classical approach to ionization in organic mass spectrometry, and only the production of ions in electrical discharges and by thermal ionization (TI) of inorganic salts have earlier been in use.
