What Does EI Stand For?

EI stands for Electron Impact

EI, or Electron Impact, is a widely used ionization technique in mass spectrometry. It involves bombarding gaseous molecules with high-energy electrons, resulting in the formation of ions through the ejection of electrons from the molecules. This method is effective for producing stable fragmentation patterns, making it crucial for the analysis of organic compounds and the identification of chemical structures. EI is particularly valuable in analytical chemistry for applications in environmental, pharmaceutical, and biochemical research.
