Kjeldahl Nitrogen Distillation FOSS Kjeltec™ 9 Analyser
Model: Kjeltec™ 9 Analyser
Manufacturer: Foss – Denmark
Product Description
Speed with Safety
The Kjeldahl distillation unit increases throughput and saves operator time with fully automated batch processing. Analyze up to 60 samples unattended and up to 240 samples in 24 hours with the Kjeltec™ 9 Autosampler.
Ensure safety with FOSS’s pioneering SAfE mode, which minimizes chemical spills while reducing cleaning and maintenance requirements.
Traceability and Reliability
Gain deep insights and full traceability with network software that collects analysis results and data from multiple devices in one location. All data is automatically recorded, backed up, and easily shared. Instant alerts in case of errors reduce downtime.
Sustainable Kjeldahl Solution
Ensure continuous high performance, minimal downtime, and optimal chemical usage while benefiting from remote troubleshooting, service, and diagnostics. Automatic sample pairing allows reference tests to be linked for easy NIR calibration development.
Features
High Accuracy with Colorimetric Titration
Classical colorimetric titration is combined with unique technologies such as automatic LED calibration and automatic endpoint detection to ensure consistently accurate results over time. The automatic endpoint detection combined with auto mode ensures each analysis is performed reliably and quickly. The new titration controller guarantees that the exact endpoint is reached throughout the distillation process.
Safe and Easy Operation
Reduce training burdens and personnel typically required for chemical analysis operations. Kjeltec™ 9 is easy to operate and provides new levels of automation to save operator time and ensure safety. Users are fully protected by the unique safety door, which must be closed with the in-place tube before the device operates.
Minimize Chemical Spills
FOSS’s pioneering SAfE mode, smart reagent addition, and minimal operator cleaning/maintenance reduce chemical exposure risks. Steam supplementation ensures balanced operation.
Alert and Notification Setup
Configure Kjeltec™ 9 to provide real-time alerts to staff in case of errors. The optional “Alerts & Notifications” service provides instant notifications of selected events, such as device or autosampler errors, via email or SMS. This allows staff to continue other tasks while analyses are running.
Accurate Results and Easy Data Handling
Data handling starts by registering and configuring sample batches. This information is transferred to your Kjeltec™ 9 Analyser via optional Kjeltec Registration PC software. Simply scan sample IDs to register and configure batches and know which test program to run.
Integration of Indirect Methods
Indirect methods can be integrated into sample preparation to eliminate guesswork in reference analysis. Screen samples using Near-Infrared (NIR) or Fourier Transform Infrared (FTIR) spectroscopy to estimate expected values for fat, protein, and moisture, ensuring the correct reference method is selected. This avoids costly reruns and reduces chemical use, saving time and money.
