SED-800TOC-H Total Organic Carbon (TOC) Analyzer using high-temperature oxidation + NDIR detection. Detects TC/IC/TOC/NPOC. TOC range 0.050–35000 mg/L, TIC range 0–30000 mg/L, detection limit 0.050 mg/L, accuracy ±5%, re
مبدأ العمل
Liquid samples are injected into a combustion furnace containing a high-performance oxidation catalyst. At up to 1100°C, organic carbon is completely oxidized to CO₂ and H₂O; water vapor is removed by a condenser, and CO₂ is quantified by a non-dispersive infrared(NDIR) detector to give TC. Inorganic carbon(IC) is liberated by phosphoric acid, condensed, and measured separately by NDIR to give TIC. TOC = TC − TIC. Carrier gas is high-purity oxygen(≥99.999%).
