Simultaneous fluorescence, photoacoustic and two-photon photoionization detection for liquids in a cuvette

Abstract:
A simple, sensitive liquid-phase photoionization detection scheme employing pulsed laser excitation has been developed. The system is an elaboration of an earlier simultaneous fluorescence and photoacoustic detection scheme employing a standard fluorescence cuvette. Factors affecting the analytical performance of the two-photon photoionization mode of operation are discussed, sensitive three-mode detection is demonstrated for a model compound (anthracene), and the effect of temperature on the photoionization mode provides an estimate of the ionic-charge carrier activation-energy in the conductance transport process.
