ABSTRACT:
Water or some other aqueous fluid is employed as the light transmitting medium of a liquid-core fiber-optic wave guide employed as a spectrophotometer cell by employing, to define the core region, a polymer having a refractive index of less than 1.33. The light conducting channel defined by the aqueous fluid filled core may be a capillary or other suitably shaped vessel. The analysis of samples is accomplished by drawing a sample into the wave guide core region throughout the use of a fiber optic piston and thereafter delivering measurement light to the sample via the piston.
