Signal detection of pulsed laser-enhanced ionization
Journal Article

· Anal. Chem.; (United States)
A point charge model based upon charge induction theory has been developed to describe the proposed detection mechanisms of laser-enhanced ionization (LEI). The model predictions are in good agreement with experimentally observed LEI electron and ion signal pulses. The predicted effects of alkali metal matrix concentration and laser beam position are also confirmed by experimental results. The development of this model provides a basis for establishing experimental methodology that is necessary for the development of LEI as a technique for trace metal analysis. 23 references, 8 figures, 2 tables.
