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.

Support for new means of communications, enhanced data handling

Compatible with digital bus standard

• Instrument operation, readout of measured values, and checking for alarms can be performed via the RS-485 or RS-232C (option). This function is convenient when managing multiple instruments.

Control sample measurements

• Periodic measurements of pre-selected control samples. This can be used to monitor the condition of the instrument. Automatic calibration can be performed when a certain reference value is exceeded.

Web-based monitoring (option)

• Installing an optional board allows connection of the instrument to a network. The optional board offers web-server functions, allowing real-time browsing of measured values and alarms with a Web browser.

 

Support for a wide range of samples

From pure water to heavily polluted water

• Measurement ranges from 5 mgC/L full-scale to 20,000 mgC/L full-scale.
  An option can be attached to support high-sensitivity measurements to 1 mgC/L full-scale.
• The pretreatment unit for heavily polluted water incorporates a unique washing function and special operation sequences to control blockages and biological contamination. This reduces the maintenance frequency.

Automatic dilution function

• TOC-4200 offers sample automatic dilution functions (×2 to ×50) as standard.
• When measuring an acid, strong alkaline, or inorganic salt sample that may damage the instrument or consumables, the effect can be alleviated by diluting the sample.
• A single high standard can be auto-diluted to make a multi-point calibration curve for laboratory time saving effort.

High-salt sample combustion tube kit

• When measuring samples with high levels of inorganic salt, such as seawater, the inorganic salt can accumulate inside the combustion tube and cause physical blockage or deterioration of the combustion tube. This kit extends the tube-replacement period approximately ten times as compared to a normal combustion tube.

 

Permits TOC measurements that match the sample's characteristics

• TOC measurement by acidify and sparge TOC also know as non-purgeable organic carbon (NPOC)
• TOC determination by difference between total carbon (TC) and inorganic carbon (IC)
• TOC = TC - IC (requires option)
• TOC determination by addition method of NPOC and purgeable organic carbon (POC)
• TOC = NPOC + POC (requires option)

Range of pretreatment units to match a sample's characteristics

• Pretreatment units are available for applications from pure water to heavily polluted water.
• Reduces instrument maintenance frequency.
• Switch between measurement points in up to six flow lines. More economical since the need for multiple instruments is eliminated

Reliable sample injection system

• A single unit performs sample intake, discharge, dilution and injection.
• Automated sample acidification and sparging.
• Highly reliable ceramic 8-port valve used to switch flow line.

 

TOC-4200 has MCERTS accreditation 

The TOC-4200 online total organic carbon analyzer has been awarded MCERTS accreditation based on established performance standards and test procedures for continuous water monitoring equipment.

MCERTS is the Environment Agency for England and Wales (UK) Monitoring Certification Programme. It provides the framework for businesses to meet quality requirements. Compliance with MCERTS gives the Environment Agency confidence in monitoring emissions to the environment.

The TOC-4200 is the only online TOC analyzer commercially available using catalytic combustion oxidation technology with MCERTS accreditation. This technology is a clear advantage for anyone interested in the analysis of water and waste with a high salt content, suspended solids or particles, and the most complex organic compounds.
