What Does FI Stand For?
FI stands for Field Ionization
Field Ionization (FI) is a gas-phase ionization technique used primarily in mass spectrometry. It involves the application of a strong electric field to a neutral gas, resulting in the ionization of molecules through field-induced tunneling. This method is particularly effective for generating ions from large, thermally labile molecules with minimal fragmentation, making it valuable for analyzing complex chemical structures and enhancing the sensitivity and specificity of mass spectrometric measurements.
