Laser videofluorometer system for real-time characterization of high-performance liquid chromatographic eluate

“…Since many PAH are highly fluorescent, and since they are conveniently separated by high-performance liquid chromatography (HPLC), a great number of methods have been developed based upon HPLC separation with fluorescence detection. In order to enhance sensitivity, the nitrogen-laser-pumped dye laser has been used as a fluorescence excitation source by many researchers (1)(2)(3)(4)(5)(6). The N2 laser provides a high peak power and a high pulse rate and is suitable for use with dyes that emit in the blue and near-ultraviolet (near-UV) regions.…”

“…Consequently, improving detection limits in the determination of the corresponding anions in aqueous solution ultimately benefit the gas-phase detection limits as well. The advent of the diffusion scrubber (4)(5)(6) has accentuated the need for fast, sensitive aqueous phase continuous flow analytical procedures; these are ideally coupled to the scrubbers. We are interested in fast and sensitive flow injection analysis (FLA) procedures for this reason, and direct application of such 0003-2700/86/0358-2839$01.50/0 &copy; 1986 American Chemical Society…”
