Abstract:
A device useful in the photo-oxidation of a sample liquid and in the measurement of the oxidized carbon content thereof, the device comprising:a cell comprising a rigid light-transmissive outer wall enclosing a continuous predetermined internal volume, the transmissivity of the rigid outer wall being sufficient to allow the passage therethrough of photo-irradiation of an intensity sufficient for effecting said photo-oxidation of said sample liquid when said sample liquid is loaded into said continuous predetermined internal volume; at least two elongate probes penetrating through said rigid outer wail and extending substantially into said continuous predetermined internal volume, the probes collectively capable of measuring the temperature and the conductivity of said sample liquid, at least one of the elongate probes being hollow at least partially along its length; and a temperature sensitive element, capable of providing a temperature-dependent electrical signal, positioned inside one of said hollow elongate probes.
