Introduction
The ELEMENTRAC CN-r by ELTRA is an advanced nitrogen and carbon analyzer designed for high-throughput laboratories. It offers fast, reliable, and cost-effective analysis using the Dumas method, providing results in less than three minutes.

Specifications
The analyzer measures nitrogen in the range of 0.03 mg to 300 mg and carbon from 0.02 mg to 175 mg. It supports sample weights up to 1.0 g and uses a thermal conductivity detector for nitrogen and NDIR for carbon. The device requires oxygen, helium, and compressed air for operation.

Design and Features
The ELEMENTRAC CN-r features an ergonomic design with an integrated PC and tiltable touchscreen. It is engineered for continuous operation and high-throughput analysis, ensuring durability and reliability. The device is compact, saving laboratory space, and uses non-aggressive chemicals for safer operation compared to the Kjeldahl method.

Performance and Efficiency
The analyzer offers fully automated nitrogen and carbon determination, with a smart processing system that allows simultaneous combustion and analysis, significantly reducing analysis time. It is more than 70 times faster than the Kjeldahl method and features intelligent gas-saving functions to lower operating costs.

Sample Handling
The ELEMENTRAC CN-r can handle a wide range of sample matrices, both solid and liquid, with high accuracy. It includes an innovative autosampler to prevent sample mix-ups and allows for priority sample processing.

Maintenance
Maintenance is straightforward, with consumables easily replaceable in under 20 minutes, minimizing downtime.

Compliance and Standards
The analyzer complies with various international standards, including DIN, ISO, AOAC, AACC, and AOCS, ensuring its suitability for diverse applications in food, feed, fuels, and fertilizers.

Conclusion
The ELEMENTRAC CN-r provides a modern, efficient alternative to traditional nitrogen analysis methods, offering significant advantages in speed, cost, and safety.
