The Kjeldahl method is the most versatile technique available for nitrogen analysis. In fact, it is the only method that can be used for analysis of nitrogen content in samples with high diversity.
The FOSS automated Kjeltec™ instruments include systems for sample digestion and distillation. The truly modular digestion system can be configured from a simple manual set-up to a fully automated system for unattended operation, making them suitable for any type of small or large laboratory. The Kjeltec series is designed to attain the best possible accuracy and precision. It also sets safety standards in Kjeldahl analysis.
Applications
FOSS can as your partner supply you with validated applications for a wide range of parameters and sample types.
The FOSS designed built in colorimetric titration gives an unmatched accuracy and precision, and is presented as the preferred methodology when new standards are issued by AOAC, ISO and other standardization organisations. Your results will be accurate from day to day and no calibration is required. There are almost 100 sample specific application notes available.
These two application notes comprehensively describe the general methodology for nitrogen/protein analysis
AN 300
The determination of nitrogen according to Kjeldahl using block digestion and steam distillation.
AN 303
The determination of nitrogen according to direct distillation (DD) using steam distillation.
Kjeltec™ 2300 Analyzer Unit
Automatic distillation and titration
System description: The Kjeltec™ 2300 incorporates an automatic distillation and titration procedure for speed and accuracy in routine analysis. Operational safety and convenience are enhanced by features such as the SAfE (Steam Addition for Equilibration) step, automatic reagent addition and tube drain, and a fully interlocked safety system. Unit robustness is increased by alkali-resistant splash head and tube emptying vessel.
A colorimetric titration system officially approved by AOAC, AACC, EPA, ISO and DIN is built-into Kjeltec 2300.
