Automatic Kjeldahl

Description:

Kjeldahl method is to convert nitrogen-containing organic  matter into inorganic ammonium nitrogen sulfate. The  protein content can be obtained by multiplying the  measured value of nitrogen content by a certain  coefficient. This method is defined as the current method  for the determination of protein content in food. National  standards and internationally accepted methods for  determination of nitrogen. The instrument is designed  according to the principle of Kjeldahl method for nitrogen  determination. The system can be used for the determination of nitrogen or protein content.

Performance Characteristics

Test automation 

Add acid, alkali, distillation, titration, result calculation and printout, automatic sample  measurement.

Sample explosion-proof boiling

The methods of sample dilution and alkali addition can be set arbitrarily according to the different  samples of users, so as to prevent the sample from bursting and boiling and improve the  measurement accuracy.

Alkali pump anti crystallization

The self-developed alkali pump anti crystallization technology solves the problem of alkali pump  crystallization and improves the reliability of the instrument.

Steam adjustable 

Steam pre adding mode, steam flow rate (1-100%) can be adjusted automatically, so as to achieve  better distillation effect and ensure the accuracy of the experiment.

Two mode titration

Double mode titration is adopted, and the combination of coarse and fine titration will ensure the  high accuracy of the results; the titration method conforms to AOAC, EPA, DIN, ISO and other  certification methods, The titration shall be conducted by the officially recognized color titration  method.

Accurate judgment of end point 

End color user fine tuning technology and end color learning technology ensure the adaptability  of accurate test and show more human care.

Empty the titration cup 

After the sample distillation, the instrument automatically completes the emptying of the residual  waste liquid in the sample tube, and the titration cup automatically discharges and cleans the  waste liquid.

Authority and tracking 

Set up five login accounts, three-level permission settings, operation log with tracking function,  and test results can be traced.

Security protection

Multiple intelligent protections, such as digestive tube in place detection, safety valve, condensate  detection, steam generator overheating, overpressure protection, liquid level detection, etc.,  ensure the instrument and operator Staff safety.
