Abstract
This invention provides devices for the measurement of total organic carbon content in water samples. The device has a microfluidic sample cell with a sample channel for receiving a water sample wherein the water sample can be irradiated with UV radiation to oxidize organics to CO . The sample channel is sufficiently thin in the region irradiated to allow very rapid substantial mineralization of the organics in the sample. A photocatalyst, such as TiO or platinized TiO can be employed to speed sample oxidation. Substantial mineralization of a sample can be achieved in less than about 30 seconds, significantly decreasing the time required for making a TOC measurement. CO generated by sample oxidation can be detected and/or quantitated by various methods, particularly by conductivity measurements or by infrared methods.
