Chemi-ionization - Wikipedia

WebChemical ionization uses a reagent gas to ionize sample molecules through ion–molecule reactions in the gas phase. The reagent gas (e.g., methane) first undergoes electron ionization, generating a molecular ion which then fragments and/or reacts with other reagent gas molecules and ions. WebDepending on the sample molecule and the reagent gas, ionization reactions include proton transfer, proton abstraction, and adduct formation. Compared to EI, CI is a soft ionization technique because the reagent gas reactions substantially reduce the energy absorbed by sample molecules, producing substantially less fragmentation or … photo boxer shorts
