ABSTRACT:
A gas chromatograph Fourier transform infrared (GC/FTIR) system includes a GC oven having a flexible capillary column therein for separating components of a sample. The column discharges effluent directly into a light pipe associated with an FTIR spectroscope. An auxiliary flow of carrier gas is added to the effluent at the light pipe to convey constituents through the light pipe free from tailing or peak broadening.
