uniTOC – UV/persulfate TOC analyzer with NDIR detection by MembraPure GmbH

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)
