Drinking Water Online Monitoring Instrument
Total Organic Carbon (TOC) 0n-line Analyzer
product details

Product Model:TOC-8000


System Description


Pretreated water sample was injected into UV dige­stion tank by injection pump. Inorganic carbon in sample reacts with strong acid and transfer to carbon dioxide , which escaped from gas-liquid separator. Then, TOC of sample is oxidized by strong oxidizing agent and transfer to carbon dioxide,which were brought into condenser by carrier gas. After Filtered solid particles and interfering substance, the condensed carbon dioxide was brought into Non-dispersive infrared(NDIR) Gas measuring room.

NDIR output signal is related to the concentration of carbon dioxide and so with TOC in water these way, The TOC value of water can be directly measured through the photoelectric signal determination.
