UniTOC

The uniTOC device uses the full oxidation by UV. The oxidation process can be enhanced with additional dosage of reagent (persulfate). By using the NDIR detector the uniTOC gives precise results in applications of ground water to ultrapure water. The NDIR detector is absolutely selective to carbon dioxide and therefore independent from conductivity and sample temperature. Measuring times are short and the continuous self-cleaning of the reactor avoids any cross-contamination.

Since the quality of the stripped gas can be low, the use of pressurised air in combination with our air filters saves money and is optionally available.

SAMPLE VOLUME FLOW

2 to 5000 ppb (low range), 15 ppb to 20 ppm (high range)-

-TOTAL ORGANIC CARBON (TOC)-RANGE

UniTOC Advantages -

NDIR DETECTOR / TOC IS DETECTED DIRECTLY OVER CO2 AND NOT VIA A 3RD PARAMETER (CONDUCTIVITY). THEREFORE NO LIMIT TO CONDUCTIVITY.
9 MONTHS UV LAMP LIFE GUARANTEE / 50% LONGER LIFE TIME RANGE THAN USUAL.
AVAILABLE FOR TWO RANGES OF TOC.
2 SAMPLE INLETS / 2 POINTS OF THE LOOP CAN BE MEASURED ,SO DOUBLE EFFICIENCY.
REMOTE SERVICE / INSTRUMENT CAN BE CONNECTED TO INTERNET TO GET SERVICE DIAGNOSIS

Options

PRESSURE REGULATOR FOR MEDIUM

If the feed pressure is higher than 1.5 bar a pressure transducer is required.

OFFLINE VERSION

An offline configuration is available for the uniTOC.

AIR FILTRATION UNIT

To use compressed air instead of oxygen or nitrogen.

HEAT EXCHANGER

Keeps the temperature below 50 °C degrees.
