Kjeltec 9 Analyser

Overview

Value

Accurate results with fast turnaround time and easy data handling. Kjeltec 9 is safe, easy to operate and simple to run with minimal operator time and reduced risk of error.

Sample Type

Raw materials and finished products in food, feed and agriculture.

Parameters

Nitrogen, protein, ammonia.

Features

SAfE
Unmatched Accuracy with Colorimetric Titration

Combined with unique technology such as automatic LED calibra­tion and automatic end-point colour, the classic colorimetric titration ensures that the results are always correct, and performance is stable over time. Automatic end point feature in combination with auto-mode ensures reliable and fast analysis. New titration controller guarantees that the correct end point is reached continuously throughout the distillation process.

Autosamplers
Safe and Easy Operations

Reduce the training and staffing burden typically associated with managing chemical analysis operations and stop worrying about safety procedures. Kjeltec 9 is easy to operate and provides new levels of automation to save operator time and ensure safety. The user is fully protected by the unique safety door which must be closed with a tube in place before the unit will operate. Reduce the risk of chemical spillage with FOSS pioneered SAfE* mode, smart filling of reagents and minimal cleaning and maintenance for the operator.

Safety Features
Easy data handling with Alerts to avoid downtime

Using the optional Kjeltec Registration PC software, simply scan the sample ID on incoming samples to register and configure sample batches and know which test programme to run. Furthemore, Kjeltec 9 provides staff with ‘real time’ notification in case of errors of selected events such as an instrument or Autosampler error, via email or text message avoiding down time and letting staff do other tasks while analysis is running.

Unmatched Accuracy
New levels of integration with indirect methods

Kjeltec 9 is equipped with near infrared (NIR) and Fourier Transform Infrared (FTIR) to get an estimate on expected values and choose the reference method for your next step with confidence. By integrating these indirect methods, errors can be eliminated and costly re-runs avoided hence saving time and money
