MembraPure TOC Analyser for 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
  • 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.
