Abstract

A laser-enhanced flame ionization detector is proposed which promises to retain the desirable properties of conventional flame ionization detectors while providing significantly lower detection limits. Experiments are described which demonstrate laser enhancement of the flame ionization detector response. Realization of the full potential sensitivity of the laser-enhanced flame ionization detector requires significant modifications to permit effective saturation of the laser absorption over a major fraction of the flame ionization zone.
