What Does EI Stand For?

EI stands for Electron Ionization

Electron Ionization (EI) is a widely used ionization technique in mass spectrometry that involves the bombardment of gaseous molecules with electrons to induce ionization. This process typically generates positive ions by removing an electron from the molecule, resulting in fragment ions that can be analyzed to determine the molecular structure and composition of the sample. EI is particularly effective for volatile and thermally stable compounds, making it a standard method in the analysis of organic compounds.
