Electron Impact Ionization (EI)

Electron Impact Ionization (EI) Definition:

In mass spectrometry, an ionization technique that involves bombarding a compound
with high- energy electrons.

Electron Impact Ionization (EI) Explained:

It is a method that involves the ionization where energetic electrons interact with either a solid, or gas phase atoms in order to make ions. EL is the most efficient and has a molecular weight of 600.
