Abstract
A method and apparatus for the measurement of total organic carbon content in an aqueous stream is disclosed. Absorbance of electromagnetic energy by the aqueous stream is measured in an optical sample cell with pulsed light at a wavelength of 190 nm±10 nm. A value of total organic carbon from the measured absorbance is calculated without absorbance or fluorescence measurement at any other wavelength.
