TOC-4200 Total Organic Carbon Analyzer (Online Type)

  • Online TOC (total organic carbon) analyzer provides Stable operation
  • Sampling units for applications from pure water to heavily polluted water
  • TN (Total Nitrogen) measurement option
  • Reliable sample injection system
  • Monitoring TOC removal rate based on EPA Regulations (optional)

Supports monitoring TOC removal rate based on EPA Regulations

  • Calculates TOC removal rate based on the United States EPA regulations
(Part IV 40 CFR Part 9, 141 and 142, 1998)
(when a 2- or more-stream switching option is provided)

Total pollutant load control regulation applications (organic pollution load)

  • Converting the measured TOC values allows applications to COD total volume control. (*1) TOC → COD conversion functions are installed as standard.
  • Reading flow rate signals from a flow meter (*2) permits COD load conversion calculations.

Wastewater treatment plant influent (upstream monitoring) and effluent

  • Measurements at a short measuring cycle (4 minutes minimum) rapidly capture dramatic changes in organic matter or abnormal effluent.
  • The powerful oxidation capacity of a combustion-type analyzer can detect organic matter that cannot be captured using a UV meter.
  • The short measuring cycle and powerful oxidation, combined with switching between up to six flow lines, offer detailed monitoring of treatment plants.

Monitoring of river water sampled at water purification plants and treated water (tap water)

  • Monitoring changes in river water quality due to rainfall and other factors to provide control indicators for treatment processes.
  • Permits simultaneous monitoring of treated tap water.

Plant water (washing water, cooling water, recovered water, boiler water, condensate, etc.)

  • Continuous monitoring of water used in a plant.
  • Continuous monitoring of pure boiler water assists in the detection of anomalies, such as damaged pipes.
  • The short measuring cycle (4 minutes minimum) of the combustion-type TOC analyzer achieves more rapid detection of anomalies.
