TOC HR M. TT

TOC is a measure of the organic carbon content of a sample or body of water. A build up of organic carbon can result in raised treatment or discharge costs. Industrial applications include cooling water discharge and the measurement of organic concentrations in steam/condensate.
Traditional methods involve UV digestion or combustion. Colourimetric TOC analysis involves heating the sample in a sealed tube with an oxidant. This converts the organic compounds to CO₂ and water, which can then be measured colourimetrically.
Although the TOC can be determined using this method, individual carbon complexes cannot be broken down and identified separately.
