Abstract

A RIS-TOF MS instrument with a modified Wiley-McLaren ion source is described. Samples are loaded onto a rhenium filament from which they are vaporised, followed by single color, three photon ionization. The instrument incorporates a Nd:YAG pumped dye laser. Two major limitations of such a design lie firstly in the chemistry of the ion source which yield both atomic and molecular species, the latter represents a signal loss or even an interference. The second limitation arises from the combination of a low duty cycle ionization laser (8 ns pulse width at 10 Hz) with a continuous atom source. Uranium has been ionized using the single-color (591.54 nm) scheme described by Donohue et al. (1) The relative merits of different filament preparation schemes are discussed and a technique is proposed that addresses sample losses due to the low duty cycle of the 10 Hz laser.
