In this work, we describe the interfacing of a high-resolution chromatographic system featuring narrow bore gas chromatographic columns to a Fourier transform infrared spectrometer. Excellent chromatographic resolution, low nanogram sensitivity, and compound identification are demonstrated. Applications to the analysis of a petroleum distillation fraction and to a polymer sample, analyzed after pyrolysis, are presented. A vapor-phase library search system is used to identify compounds in both samples.
