Sophisticated Technologies for Your TOC/TNb Analysis
From surface and waste water investigations in the environmental sector to high-purity water in the semiconductor or pharmaceutical industry – our multi N/C instruments offer you customized solutions for reliable TOC/TNb measurements in your field of application. Especially in the case of difficult sample matrices, the devices are convincing due to their reliability and ease of maintenance. With the new multi N/C duo systems we also offer combined analytical instruments for fully automated liquid and solid TOC analysis.
At the heart of each model of the multi N/C series is the corrosion-free Focus-Radiation NDIR detector. Over a measuring range from 0 to 30,000 mg/L TOC it achieves highest sensitivity and precision without sample dilution. The VITA Flow Management System effectively compensates for carrier gas fluctuations and enables automatic and long-term stable calibration with EasyCal.
Two sample digestion methods are available for TOC measurement: high-temperature combustion up to 950 °C and wet chemical UV oxidation. The high-power long-life UV reactor uses two wavelengths (185/254 nm) for complete oxidation, enabling blank value-free analysis without oxidizing agent. Furthermore, numerous liquid and solid automation options, nitrogen detectors and solid modules are available. With our broad product range it's your choice to benefit from our proven technologies of different sample digestion techniques like high temperature combustion or UV digestion as well as different sample injection techniques, direct or flow injection and varios automation solutions.

Smart Solutions for Convenient TOC/TNb Analysis
Reliable detection – Focus Radiation NDIR detector
The heart of every multi N/C device is the Focus Radiation NDIR detector for CO2 detection. High-energy IR radiation is focused on the micro detector by means of integrated optics. The obtained radiation density exceeds classical detectors and guarantees higher sensitivity and precision over a measuring range from 0 to 30,000 mg/L TOC without sample dilution. You save on operating costs thanks to corrosion- and maintenance-free operation and a long-term warranty of ten years.
Reliable digestion − high-power long-life UV reactor
The high-power long-life UV reactor uses two UV wavelengths simultaneously for oxidation (254/185 nm). This high-energy radiation ensures fast and complete digestion even of very stable carbon compounds. Therefore, additional reagents are not required for many applications or can be prepared by the user. Together with the three-year warranty for the UV reactor, this leads to minimum running costs.
Reliable performance – VITA and Easy Cal
The VITA Flow Management System allows for the rapid injection of large sample volumes into high temperature TOC analyzers and significantly improves result accuracy and sensitivity in the trace range. In addition, Easy Cal makes it possible for multi-point calibrations to be performed from a single stock solution using different injection volumes. The generated calibration curves are independent of the injection volume and extremely long-term stable. The automatic and correct calibration range selection for each sample measurement allows for easier operations at the highest level.
