Abstract
Techniques for increasing the sensitivity of the interface between a gas chromatograph and a rapid-scanning Fourier transform infrared spectrometer (GC-IR) have been developed. A single-beam system, in which a triglycine sulfate (TGS) detector is used to measure the interferogram, has been designed and constructed. Identifiable infrared spectra of submicrogram quantities eluting from a gas chromatograph have been measured without trapping the sample using this system. A double-beam configuration for GC-IR has also been designed so that a cooled mercury cadmium telluride detector can be used to further decrease the detection limits without limiting the sensitivity by digitization noise. Each of these systems necessitates the use of light-pipes with relatively long (30 cm) absorbing paths but low reflection losses.
