Abstract

Shown schematically in the figure is a system for analyzing, by infrared (IR) techniques, the constituents of a sample which have been separated by a liquid chromatograph (LC). A tape or belt 1 moves from a supply reel 2 to a take-up reel 3. A thermal spray device 4 receives the solvent plus sample constituent output from an LC, separates the solvent, and directs the constituents onto moving belt 1. The constituents are then carried through a test area where IR energy from a source 5 is directed onto the belt and reflected into a diffuse reflectant detector 6 for analysis by an FTIR spectrometer. To enhance the diffuse reflectance sensitivity, belt 1 is coated with a powdered salt, such as KCl, KBr, etc.
