Abstract

Earlier work in this laboratory has shown matrix isolation Fourier transform infrared spectrometry (MI FTIR) to possess several advantages over conventional sampling techniques for the qualitative analysis of complex samples. The ability to obtain very sharp spectra using MI makes it possible to distinguish between very similar compounds, including isomers, present in a sample. Instrumentation to couple capillary column gas chromatography (GC) to MI FTIR has been developed as an alternative to on-the-fly gas-phase GC FTIR measurements. This technique allows leisurely study of chromatographic fractions at medium resolution (1 cm^-1). A gold-plated disk is cooled to 15K with a closed-cycle helium refrigerator and used to collect compounds eluting from the GC. Nitrogen is used as both GC carrier gas and matrix material. Beam condensing optics and KRS-5 rods are used to reflect the IR beam from the individual sample deposition surfaces.
