ABSTRACT:
An apparatus and method are disclosed for measuring the fluorescence and absorbance of a liquid sample. A sample tube is provided that has an external surface and a bore therethrough for containing a sample fluid. A cladding fluid coats the bore of the sample tube to provide a smooth surface adjacent to the sample fluid. Excitation radiation is directed along the bore and detector means are provided to detect the excitation radiation, fluorescent radiation, and non-absorbed radiation. Comparator means compare the signals from the presence and concentration of various constituents in the liquid sample.
