Vario TOC Cube

Vario TOC Cube

For the first time the ppb-sensitivity for measuring TOC or TNb in aqueous solutions is combined with the accuracy and reliability of organic elemental analysis to measure up to 100% carbon concentrations in any sample matrix.

Features

  • Oxidation of bound carbon by means of high temperature digestion and catalytic post combustion in a free selectable range of up to 1,200 °C.
  • Measuring modes for TC/TIC, TOC/NPOC, POC and DOC
  • Formed CO2 is purified through a halogen trap with a subsequent 3-step intensive gas drying system
  • CO2 detection by a super wide range NDIR-photometer with extraordinary linearity. Free of spectral interferences even against SO2 and an outstanding concentration range without sample dilution
  • Newly developed matrix separation system serves for long lasting uninterrupted operation times even for mineral containing samples (e.g. sea water)
  • Determination of bound total nitrogen (TNb) as NO by means of optional electrochemical sensor (EC), infrared- (NDIR) or chemiluminescence detector (CLD) down to ppb level
