Abstract
A flow through photochemistry apparatus and methods of use are disclosed in the present application. One or more reactant materials are passed through a reaction chamber and are exposed to electromagnetic radiation. The reaction chamber has reflective walls arranged to reflect electromagnetic radiation across the volume of the chamber a plurality of times, thereby increasing the probability of the electromagnetic radiation interacting with the reactive materials. The reaction chamber may be used for sterilization and photochemistry applications.

Apparatus for applying electromagnetic radiation to reactant materials in a reaction chamber comprising:
- a reaction chamber defined by at least one reflective surface arranged to provide multiple reflections to increase the optical path length of the electromagnetic radiation through the reaction chamber;
- wherein said at least one reflective surface is formed by a mirror layer carried on a substrate;
- wherein the electromagnetic radiation is introduced into the chamber by at least one LED;
- wherein the LED is carried on the substrate;
- and wherein the substrate carries electrically conductive components of an electrically conductive layer for providing power to the LED.
