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.

Carbon / Nitrogen / Protein Analyzer ELEMENTRAC CN-r Operation and Analysis Process
Step 1: Registration of the Sample in the Elements 4.0 Software
The sample is registered in the ELEMENTS 4.0 software. The weight is automatically transferred from the balance (step 1) – fast, safe, and error-free.
Step 2: Weighing and Application
Whether a few milligrams or up to 1 gram: the ELEMENTRAC CN-r offers the highest precision with various sample types – solid or liquid. These are simply weighed into tin foil or tin capsules and reliably analyzed.
Step 3: Analysis
The samples are conveniently placed into the carousel. The CN-r automatically detects the carousel and clearly assigns all samples – ensuring a smooth, safe, and automated process.
Step 4: Data output and export
120 to 180 seconds after the analysis has started, the measured concentrations are available for export as a report or via LIMS.

Integrated standard solutions
All chemicals required for operation are ergonomically arranged at the front and safely hidden behind a door during routine use. Maintenance is especially user-friendly: combustion and reduction tubes can be replaced without tools in just a few minutes. This well-thought-out design reduces time expenditure, increases reliability, and ensures maximum reproducibility of your analyses.
Touchscreen & Integrated PC
The ELEMENTRAC CN-r is equipped with a modern touchscreen that can be placed flexibly either directly on the device or conveniently on the desk. Thanks to the integrated PC, no additional hardware is required. The ELEMENTS 4.0 software can be intuitively operated via touchscreen – or classically with a keyboard and mouse. With the available USB ports, you can easily connect peripheral devices such as a keyboard, mouse, or a balance.
Networking & Data Access
The CN-r can be easily integrated into your network. This allows you to transfer results directly into your LIMS or access the device software from your office PC. Whether recalculations, evaluations, or entering new samples: you always have full access and can complete your tasks easily and efficiently – regardless of the device’s location.
High Performance
Analyze your samples in less than 3 minutes! Our intelligent processing allows simultaneous combustion of the current sample and analysis of the previous sample (so-called interleave analysis). Get results over 70 times faster than with the Kjeldahl method and benefit from unparalleled speed in your analysis workflow.
Effortless Maintenance
All consumables can be replaced in less than 20 minutes, keeping your system always ready for use. An optimized workflow with quick and effortless maintenance ensures smooth operation with minimal downtime.
