A process for using photocatalytic load reduction to extend reactive media filtration life is disclosed for an air purification system. The system consists of three methods of cleaning the air including a UV light, a photocatalyst, and an air purifier. Air first passes through a portion with the UV light and photocatalyst, and then through the purifier. Passing the air first through the UV light and photo catalyst before the purifier reduces the load on the purifier and thus allowing the purifier to operate and clean the air for an extended period of time as compared to the purifier alone.

Photocatalytic load reduction to extend reactive media filtration life in an air purification system

A flow cell and method for photometric transmission measurements are disclosed in which a folded optical path provides for co-located, collinear fiber optic read and illumination cables that can be bundled together. Light passes through a fluid sample, is reflected off a pair of right-angle turning mirrors and returns through the fluid for a second pass. A center divider separates fluid passages on the first pass of the light through the fluid and the second pass of the light through the fluid to block any undesired backscattered light from reaching a detector.
