The Kjeltec™ 9 series provides safe and accurate distillation with various levels of automation to meet the needs of your laboratory. Alongside a Kjeltec™ 9 Autosampler, the Kjeltec™ 9 Analyzer offers the highest level of automated Kjeldahl analysis.
Speed with safety
Increase throughput and save operator time with fully automated batch handling. Analyse up to 60 samples unattended and up to 240 samples in 24 hours with KjeltecTM 9 Autosampler. Ensure safety with FOSS pioneered SAfE mode reducing the risk of chemical spillage while minimising cleaning and maintenance.
Lab operations built on traceability and trust
Gain insight and traceability with networking software that collects analytical results and data from different instruments all in one place. All data is recorded and backed up automatically and is easy-to-share. Instant notifications in the case of errors reduce downtime.
Total solution for sustainable Kjeldahl
Ensure continuous high performance, minimal downtime and optimal use of chemicals and benefit from remote troubleshooting, service and diagnostics. Automatic sample matching makes it easier to pair reference tests for calibration development of NIR options.
Sample type
Raw materials and finished products in food, feed and agriculture.
Parameters
Nitrogen, protein and ammonia.
Technology
Kjeldahl and other nitrogen based chemical analysis.
The superior performance of a FOSS Kjeldahl titration system is based on colorimetric measurement of a precise chemical reaction for end-point detection.
Verified methods
Kjeltec™ 9 is verified against official standards such as AOAC, EPA, DIN, GB and ISO for simplified validation.
