1. Apparatus for measurement of total organic carbon contained by a sample of deionized water, comprising:

  • a sample cell having a window;

    a source of ultraviolet radiation of a frequency which causes oxidation of organic carbon compounds in a water sample disposed in juxtaposition to said window, the window being substantially transparent to said radiation;

    a pair of electrodes disposed in said sample cell;

    means rendered photocatalytic active in response to said ultraviolet radiation for providing oxidative species in said sample cell;

    means for monitoring the electrical conductivity of the water between said electrodes and means for correlating the conductivity of the water sample to its total organic carbon content.
