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.
Claims19
A method for applying electromagnetic radiation to reactant materials in a reaction chamber comprising:
- providing at least two reflective surfaces at spaced positions so as to cause reflections back and forth between the two reflective surfaces and thus increase the probability of interaction of the electromagnetic radiation with the reactant materials by increasing the optical path length of the electromagnetic radiation;
- wherein the chamber is shaped to define an optical axis between said reflective surfaces;
- wherein the electromagnetic radiation is introduced into the chamber by at least one source arranged to emit the electromagnetic radiation mainly in the direction of the optical axis.
A method for applying electromagnetic radiation to reactant materials in a reaction chamber comprising:
- providing at least two reflective surfaces at spaced positions so as to cause reflections back and forth between the two reflective surfaces and thus increase the probability of interaction of the electromagnetic radiation with the air flow by increasing the optical path length of the electromagnetic radiation;
- wherein the surfaces are shaped to define an optical axis of said at least one reflective surface;
- wherein the electromagnetic radiation is introduced into the chamber by at least two sources;
- wherein said at least one source is located at a position spaced outwardly from the axis;
- and wherein said at least one source and the axis arranged such that the back and forth reflections create a virtual source symmetrically located around the axis at a position 180 degrees relative to said at least one source.
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 the electromagnetic radiation is introduced into the chamber by at least two LED sources;
- and wherein the LED sources include separate heat sinks separated by enough that little heat diffuses between the LED sources.
