The TOC-230D utilizes the principle of high-temperature catalytic oxidation combined with NDIR detection (dry method) to measure TOC concentrations in water samples ranging from 0.05 mg/L to 35,000 mg/L. The water sample is introduced into a combustion furnace containing a high-performance oxidation catalyst, where it undergoes complete combustion and decomposition into carbon dioxide and water vapor at high temperatures. After passing through a condenser to remove the water vapor, the resulting carbon dioxide enters a Non-Dispersive Infrared (NDIR) detector. This process determines the concentration of Total Carbon (TC) in the water sample; the Total Organic Carbon (TOC) value is then calculated using the formula: TOC = TC - TIC.
