Abstract

The effluent from a gas chromatograph (GC) is directed through a light pipe 6 for analysis by the use of infrared (IR) energy passed through the light pipe. Shown in the figure is a schematic view of an optical system for conducting IR energy through the light pipe.

GC-IR Optic Interface

The effluent from a gas chromatograph (GC) is directed through a light pipe 6 for analysis by the use of infrared (IR) energy passed through the light pipe. Shown in the figure is a schematic view of an optical system for conducting IR energy through the light pipe.

The system comprises a source 1 of infrared energy. A mirror 2 directs energy from the source into an interferometer 3 which may be of the Michaelson type. Light from the Interferometer enters a coupler 4. Fiber-optic cables or bundles 5 and 7 direct light from coupler 4 through light pipe 6 and into another coupler 8 attached to a detector 9. The material within the fiber optics is transparent to mid-infrared radiation (8,000-400 cm(-1)).
