uniTOC Analyzer
TOC Analysis from Ground Water to Ultra Pure Water
Key Features
- 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.
