ABSTRACT:
The chemical properties of a flowing liquid analyte, the analyte comprising a solvent having an index of refraction which is the same as or closely approaches that of water, are determined by liquid chromatography or capillary electrophoreses wherein the analyte is caused to flow through an optical waveguide. The waveguide is a rigid capillary having a refrctive index of less than 1.33. Measurement light is launched axially into the analyte by inserting an optical fiber, coupled to a light source, into one end of the waveguide.
