• Resumen

  • Fourier-transform infrared (FT-IR) spectroscopy plays a small, though occasionally crucial, role as a detection technique in gas chromatography (GC). FT-IR can be used as a universal, a selective and a specific detection method, but a major drawback is its lack of sensitivity. The power of GC/FT-IR is the unique structural information that can be extracted from the spectral data and that cannot be obtained from any other method. As a consequence, GC/FT-IR is mainly applied as an additional tool to GC/MS, for isomer discrimination and structure elucidation of compounds with closely-related structures.
