Ionization Techniques Mass Spectrometry

Ionization is a chemical technique used in mass spectrometry. it deals with the ion-molecular chemistry. Gas molecules are ionized by electron ionization where the reactions are carried through the gas phase with analyte molecules to achieve ionization. Proteins, peptides, oligosaccharide are the compounds which are analyzed by Mass Spectrometer. These applications of ionization techniques are extended to biochemical, biological and medicinal fields also.
