Abstract
The frequency-doubled 514-nm argon-ion laser line providing excitation at 257 nm is combined with an intensified linear diode array (ILDA) detector to enable on-the-fly identification by laser-induced fluorescence (LIF) in conventional-size column liquid chromatography (LC). The potential of this detection system is demonstrated for the analysis of a standard mixture of polynuclear aromatic hydrocarbons (PAHs). Detection limits are at the 1.5 μg 1−1 level (15 pg injected); the identitication limits are about one order of magnitude higher.Keywords
