uniTOC Analyzer

TOC Analysis from Ground Water to Ultra Pure Water

NDIR / TOC is detected directly over Carbon Dioxide and not via a 3rd parameter (conductivity). Therefore, no limit to conductivity.
Available for two ranges of TOC
9 months UV lamp life guarantee / 50% longer life
2 sample inlets / 2 points of the loop can be measured, so double efficiency
Remote service / online service diagnosis

OVERVIEW

Designed for Total Organic Carbon Analysis of Ground Water and Ultrapure Water

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 pressurised 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 realised by the periodic performance of system suitability tests.
