The DC150e Total Organic Carbon (TOC) analyzer employs a dual-wavelength UV oxidation + direct conductivity detection principle, ensuring precise measurements with excellent data repeatability. As an online detection instrument, the water sample is divided into two equal-flow streams upon entering the instrument. One stream passes through an oxidation reactor, where the organic matter is completely oxidized, while the other stream remains unoxidized. The conductivity of both streams is then measured in a conductivity cell to determine the change. Using the formula: TOC = TC – IC, the final TOC concentration in the sample is obtained.
