Abstract
A method for modifying a carbon thermal ionization filament is disclosed. In particular, the method requires a step of reacting a fluorine-containing compound with the carbon thermal ionization filament to provide a fluorinated carbon thermal ionization filament. Such method can result in a fluorinated carbon thermal ionization filament that can be employed in a system, such as a thermal ionization mass spectrometer, for ionizing a sample.
