The method describes how to determine the organically bound carbon in drinking water photometrically with a cuvette test.
Drinking water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
Total carbon (TC) and total inorganic carbon (TIC) are converted into carbon dioxide through oxidation (TC) or acidification (TIC). The CO2 is transferred from the digestion cuvette through a membrane into the indicator cuvette. The color change of the indicator is measured in a photometer. TOC (total organic carbon) is determined as the difference between the values for TC and TIC.
