GC/IR Optimal Design, A Comprehensive Study

A theoretical model for the optimum optical design of lightpipe GC/FT-IR systems was developed. This model predicts the optimum optical design based on the maximum spectral signal-to-noise (S/N) for a given lightpipe size. Experimental measurements were made to confirm the accuracy of this model and a GC/FT-IR system based on this model was built and tested.
