• Independent R&D team, can design various specific programs according to the needs of customers.

Operation principle
oxidation organism by UV lamp and convert organic stuff into carbon dioxide, which detection adopted by direct conductivity method. The total organic carbon is the difference of the total carbon (TC)concentration in samples tested after oxidation and not oxidation of the sample total inorganic carbon(TIC), namely: TOC = TC- (TIC).
