Perfect for environmental and offline process monitoring applications
High sample throughput
Variable injection and sample digestion techniques
Highest matrix tolerance and cost efficiency
The TOC and TNb contents have established themselves as reliable indicators for the quality assessment of water and solids, such as soils or recycling materials, in environmental monitoring and industrial processes as parameters that can be determined quickly and easily.
The multi N/C series offers optimised instrument solutions for a wide range of requirements in these areas, with which you can determine TOC/TNb contents efficiently and reliably and work in compliance with standards, for example in the analysis of drinking and surface water, municipal and industrial waste water, process water, such as cooling and boiler feed water, electrolysis baths or as quality parameters in the chemical industry.
Efficiency and high throughput
Automate your processes with versatile auto samplers and other efficiency-enhancing features such as integrated sample homogenization by magnetic stirring, automatic acidification and parallel purge and analysis. Depending on your requirements, processes can be optimized from samplers for small sample sequences to autosamplers with a capacity of 146 samples for high-throughput analysis.
With a separate solids module, you can also analyze solid samples directly for their TOC content. The samples are decomposed at up to 1300 °C in the robust ceramic combustion tube without the use of catalysts. Thanks to built-in valve technology, you can quickly switch between liquid and solid operation.
Long service life thanks to proven furnace technology
The catalytic high-temperature combustion at up to 950 °C enables the complete oxidation of stable macromolecules and particle-containing samples and also enables simultaneous TNb determination. Efficiency and reliability characterize our furnace technology in this field. We can proudly offer a 10-year long-term warranty* on our furnace technology. In addition, the optimized design of the combustion tubes minimizes the use of expensive catalysts and simultaneously increases tolerance to saline matrices. We thus offer you extended maintenance cycles and minimized operating costs.
