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 ultra pure 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 pressurized air in combination with our air filters saves money and is optionally available.
Calibration and SST of the uniTOC is easy and can be done by the user.
Online operation is interrupted briefly for the system checks to be performed.
The operator simply has to connect the inlet with the calibration standard solutions and the diluting water sample.
The software enables the user to perform calibration and SST independently and the programmable sequence ensures the automatic procedure and data evaluation of the test.
The verification of the TOC results according to the requirements of USP and Ph.Eur is realized by the periodic performance of system suitability tests.

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