English Abstract Liquid chromatography coupled with Fourier transform
infrared specrometry (FT-IR) was applied to the analysis of impurities in a
sample of synthesized 1-choropyrene. The method was used to identify
compounds with closely related structures in addition to gas
chromatography-mass spectrometry. All previously detected components were
separated and the corresponding FT-IR spectra were recorded. The presence
of pyrene and 1-chloropyrene was confirmed by comparison with reference
spectra. 1,3,6-trichloropyrene and the isomers 1,3-, 1,6- and
1,8-dichloropyrene were identified by interpretation of the
spectra.
