Paper Abstract

The "on-the-fly" acquisition of infrared spectra from the vapor eluting from a gas chromatograph has become a routine analytical technique. From the spectroscopic viewpoint, GC/IR appears to be a very simple experiment, and yet in many ways, the technique places the greatest demands on both the hardware and the software of any infrared experiment. The fact that the gas chromatograph vaporizes and ideally separates the sample means that the spectrometer is observing vapor phase, ambient pressure and pure compounds. While this may seem ideal, the sensitivity requirements and data acquisition rates required for real time GC/IR can be obtained only with an optimally designed system.
