The uniTOC uses the principle of full oxidation by UV. The process can be enhanced with an additional dosage of reagent (Phosphoric acid/Persulfate). The carbon dioxide produced by decomposition is quantified by the NDIR detector and the TOC value is calculated.
uniTOC advantages:
- NDIR detector - TOC is detected directly over CO2 and not via a 3rd parameter (conductivity), therefore there is no limit to conductivity.
- Available for two ranges of TOC
- Nine-month UV lamp life guarantee - 50% longer lifetime range than usual
Specifications:
- Method & detection: UV oxidation (full) & NDIR
- Sample volume flow:
- 20 mL (low range)
- 5 mL loop (high range)
- TOC range:
- 2 to 5000 ppb (low range)
- 15 ppb to 20 ppm (high range)
- Related norms: USP <643>, EP 2.2.44, DIN EN 1484, DIN 32645, 21 CFR part 11, IP 45
Simulation of the online determination of the TOC content with uniTOC of media containing boric acid as cooling water, used in circuits of plants
In this application note, MembraPure GmbH demonstrate how the uniTOC can be used for TOC detection of water mixed with boric acid, used as cooling media in circuits of plants.
