ABSTRACT:
A device useful as a detector for fluid (liquid or gas) chromatograph effluent comprising a light source, a cell divided into sample and reference fluid compartments separated by an opaque diaphragm sufficiently thin to form a Fraunhofer diffraction pattern, means to introduce and remove sample and reference fluids to and from said compartments, means to collimate light from said light source at said diaphragm and through the compartments of said cell, photodetector means capable of sensing phase shift of said diffraction pattern, and means to focus light exiting said compartments on said photodetector. When used as a detector for chromatograph effluent the sample compartment should have a volume less than the smallest volume of eluted fractions from the chromatograph with which the device is used. An especially significant and novel feature of the device is the cell used in the refractometer.
