Abstract
A sub-nanosecond tunable dye laser pumped by a transversely-excited atmosphericpressure nitrogen laser is combined with a time-resolved fluorescence detection system, consisting of a microchannel plate photomultiplier, a sampling oscilloscope, and microcomputer data-processing equipment. This system has a time resolution of 1.4 ns, and is used for determinations of traces of polynuclear aromatic hydrocarbons, in conjunction with high-performance liquid chromatography. The advantages of time-resolved detection are illustrated. Benzo(a)pyrene is determined in samples obtained from airborne particulates.
