Abstract
A modified reflectron time-of-flight mass spectrometer is developed using UV laser-induced desorption ionization with prism internal reflection. Theoretical calculations indicate that mass resolution of over 10 6 is possible if a picosecond laser and appropriate electronics are available. By ionizing aniline ( m = 93 u) with a 2 ns pulsed UV laser, mass resolution of 11 000 has been experimentally achieved. Some of the advantages of this new mass spectrometer are discussed.
