Abstract
Fluorescence measurements are easily made with the aid of a cryogenic fiber optic probe. Emission wavelength time matrixes, excitation emission matrixes, and time-resolved excitation emission matrixes are rapidly collected with a pulsed tunable dye laser, a spectrograph, and an intensified charged-coupled device. Compound identification is based on spectral and lifetime information. The potential of this approach for supporting high-performance liquid chromatography analysis and for the direct determination of benzo[a]pyrene without previous separation is demonstrated.
