Latest Patents
David A Shaw holds a patent for a refractive index detector. This device comprises a waveguide, means for contacting the waveguide with a fluid, a light source, and means to transmit light into the waveguide. It also includes means for detecting light exiting from the waveguide as an indication of the refractive index of the fluid. The invention features a mechanism to automatically change the angle of incidence of the light entering the waveguide in response to changes in the refractive index of the fluid. A preferred embodiment of the detector is designed for use in gradient elution chromatography, which includes means to indicate the rate of change of the refractive index. The use of a movable prism is preferred for adjusting the angle of incidence, and a monochromatic light source is recommended for optimal performance. Additionally, reference means are provided to compensate for changes in the intensity of the light output from the light source.
