A luminescence detector with a liquid-core waveguide. For detecting photoluminescence, the exciting radiation is provided transversely instead of axially, thus eliminating the need for monochromators and focusing optics. For detecting chemiluminescence, the chemiluminescent reagents are mixed in situ in the detector, thus eliminating time loss which results in loss of chemiluminescence. A further aspect of the invention is the electrogeneration of an unstable reagent for the production of chemiluminescence. The unstable reagent is generated in such a way that there is complete separation of anodic and cathodic products without the use of a physical barrier.

[ I claim:] [1.]1. A photoluminescence detector, comprising:(a) a liquid-core waveguide comprising a transparent tube having first and second ends, for containing a liquid which can emit photoluminescence;(b) a light source which can provide radiation suitable for exciting the liquid to emit photoluminescence, the radiation from the light source being provided transversely with respect to the liquid-core waveguide tube; and(c) a photodetector, for detecting photoluminescence emitted by the liquid in the liquid-core waveguide tube; liquid-core waveguide tube being made of or coated with an amorphous fluoropolymer which is a copolymer of tetrafluoroethylene and perflluoro-2,2-dimethyl-1,3-dioxole.
