ELEMENTRAC CN-r Carbon / Nitrogen / Protein Analyzer

The ELEMENTRAC CN-r is the perfect solution for high-throughput laboratories needing fast and reliable nitrogen, protein, and carbon determination. This analysis method, known as Dumas analysis or the Dumas method, is a proven alternative to the traditional Kjeldahl method for determining total nitrogen and protein by combustion of the sample.

State-of-the-art hardware and an integrated PC with touchscreen allow the operator to monitor the process and control all parameters. The compact design of the ELEMENTRAC CN-r saves laboratory space. The use of non-aggressive chemicals ensures higher work safety compared to the Kjeldahl method.

Typical samples for the Dumas combustion analyzers are natural products of various compositions. The ELEMENTRAC CN-r ensures complete combustion analysis of all samples thanks to the use of a pure oxygen atmosphere during the process. Combined with the highly efficient, chromium-free catalyst, all components are fully oxidized. This prevents the formation of soot and liquid tin, contributing to the stability and accuracy of the results. Furthermore, method optimization is greatly simplified by the excess oxygen during combustion in the ELEMENTRAC CN-r.

The innovative autosampler of the ELEMENTRAC CN-r ensures clear sample identification, preventing mix-ups even in a busy laboratory environment and making it easier to handle a large number of samples.
