Model :Büchi KjelMaster K-375
Automated TKN determination in sludge, soil, and waste.
The Büchi KjelMaster K-375 is a fully automated Kjeldahl system integrating digestion, distillation, and titration for rapid, accurate total Kjeldahl nitrogen (TKN) and protein determination. It delivers reliable, high-throughput data for environmental, waste, and agricultural analysis.
- Total Kjeldahl Nitrogen (TKN) Determination
- Automated Digestion and Distillation
- High-Precision Quantitative Analysis
Overview
Our center is equipped with a Büchi KjelMaster K-375 Kjeldahl Nitrogen Analyzer, a state-of-the-art automated system for determining organic nitrogen and ammonia nitrogen in solid and liquid samples. The instrument streamlines the classical Kjeldahl workflow from acid digestion to final titration, ensuring consistent and reproducible results.
This analyzer is essential for nutrient profiling in sludge, compost, soil, and wastewater, supporting waste characterization, agricultural reuse assessment, and circular economy nutrient recovery projects
What It Measures
The system quantifies total organic nitrogen and ammonia nitrogen through acid digestion, alkaline distillation, and acidimetric titration. The result provides a comprehensive measure of nitrogen content in diverse matrices.
-
Total Kjeldahl Nitrogen (TKN) Sum of organic nitrogen and ammonia nitrogen in solid or liquid samples.
-
Protein Content Nitrogen content converted to protein equivalent for biomass, feed, or food matrices.
-
Ammonia Nitrogen Free ammonia fraction in liquid samples, determined by selective distillation.
Key Applications
The Kjeldahl nitrogen analyzer provides critical nutrient data for waste characterization, soil fertility assessment, and environmental compliance.
-
Waste Characterization Determines TKN in sludge, compost, and organic waste for nutrient value.
-
Soil Fertility Testing Quantifies organic nitrogen in soil for agricultural and remediation use.
-
Wastewater Monitoring Measures nitrogen load in effluents for regulatory discharge compliance.
All devices are operated within standardized laboratory workflows to ensure accuracy, traceability, and compliance with analytical standards.
