Electron capture ionization (ECI) is a process in mass spectrometry and other forms of analytical chemistry where an electron is captured by an atom or molecule, typically resulting in the formation of a positively charged ion. This ionization technique is distinct from other ionization methods as it involves the interaction of low-energy electrons with neutral species.
