Patent ID: 11567043

Abstract:
Disclosed is an organic carbon detector that can be used with a liquid chromatography equipment such as a size exclusion chromatography. The organic carbon detector contains a carbon oxidization subsystem and a stripping and CO2 detection subsystem arranged and detachably connected with each other in said order. The carbon oxidization subsystem contains a microfluidic agent injection module (1), an inorganic carbon removal module (2), a microfluidic ultraviolet oxidation module (3) and a vacuum pumping system (4), configured to remove inorganic carbons and oxidize organic carbons. The stripping and CO2 detection subsystem contains a stripping module (7) and a CO2 detector (12), using a carrier gas to transfer the organic carbon converted gas to the CO2 detector (12). Also disclosed is a method of using the organic carbon detector in water quality monitoring.
