CONTINUOUS ION SOURCE FOR A TIME-OF-FLIGHT MASS SPECTROMETER
Improved performance of continuous ion sources in a time-of-flight mass spectrometer was obtained. The system was developed for use with heated filament surface ionization sources; however, the advantages of its use with an electron bombardment source seem more significant. With an electron gun operating continuously, a factor of 300 increases in sensitivity over that of the pulsed mode of operation is attained with improved resolution and no increase in the ratio of noise to signal.
