  • TOTAL ORGANIC CARBON (TOC) FLUID SENSOR
    Publication number: 20120180554
    Abstract: A total organic carbon (TOC) fluid sensor (100) is provided according to an embodiment of the invention. The TOC fluid sensor (100) includes a first oxidization cell (101A), a second oxidization cell (101B), a gas permeable membrane (106) configured to allow carbon dioxide to equilibriate between the first oxidization cell (101A) and the second oxidization cell (101B), a first conductivity sensor (136A), and a second conductivity sensor (136B). The TOC fluid sensor (100) oxidizes a fluid portion in the first oxidization cell (101A) to create carbon dioxide, equilibriates the carbon dioxide between the first oxidization cell (101A) and the second oxidization cell (101B), obtains a second cell conductivity information, and determines a TOC quantity in the fluid under test from the second cell conductivity information when the first cell oxidization is substantially complete.
