Abstract

Liquid chromatography (LC) was coupled semi on-line to Fourier transform infrared spectrometry (FT-IR) using a spray-jet assembly interfaceto eliminate the LC eluent prior to IR detection. The usefulness of the LC-FT-IR system in the identification of closely related compounds in complex mixtures is demonstrated by the analysis of a chlorinated pyrene sample which contains a number of chloropyrene isomers and congeners. Characteristic FT-IR transmission spectra of all constituents could be recorded. Since most of these compounds have not been analysed by IR before, spectral assignment was mainly based on the empirical Hansen-Berg rules for substituted pyrenes. The identification limits forthe chloropyrenes typically were 5-10 ng injected.
