Automatic Kjeldahl Nitrogen Analyzer
The Digest Furnace Kjeldahl Nitrogen Analyzer is an automated, high-precision nitrogen testing system engineered to deliver accurate and time-efficient nitrogen determination through an integrated workflow of digestion, distillation, and titration for laboratories managing medium to high sample volumes.
The Digest Furnace Kjeldahl Nitrogen Analyzer is designed for precise nitrogen determination using the classical Kjeldahl method. This fully integrated system combines digestion, distillation, and titration into a single automated workflow, ensuring high accuracy with minimal operator involvement. It is an ideal solution for laboratories handling medium to high sample throughput.
The automated Kjeldahl distiller performs real-time titration simultaneously with distillation, merging both processes into one continuous operation. This significantly reduces total analysis time. An additional advantage of this system is its ability to automatically detect when nitrogen release from the sample is complete, allowing the distillation process to stop at the optimal point. This ensures maximum nitrogen recovery without unnecessary prolongation of the process.
Advanced Digestion and Distillation System
- The digestion furnace system is a robust unit featuring an automated tube rack that enhances safety, operational convenience, and flexibility during Kjeldahl analysis. The system supports PC connectivity, enabling full traceability and data logging throughout the analytical process. Automatic lifting and handling functions eliminate the need for manual intervention, improving both efficiency and safety.
- Designed for ease of operation, the analyzer minimizes the use of chemicals and reagents while saving time, space, and energy. It is fully compatible with gas washing (scrubber) systems, preventing the release of nitrogen oxides and other harmful gases into the laboratory environment.
- The integrated scrubber system collects gases produced during acid digestion, condenses them, and neutralizes all waste before discharge. This protects the vacuum pump, extends equipment lifespan, and ensures a safe working environment.
Intelligent Software and Accessories
- The system includes dedicated control software that manages automation and ensures all routines operate smoothly. The software can be customized based on specific user applications, allowing full control and monitoring of digestion and distillation parameters.
- A complete range of high-quality accessories and consumables is available, including catalyst inserts with multiple formulations to suit different raw materials and digestion requirements.
