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.
The Kjeldahl method involves transforming nitrogen-containing organic substances into inorganic ammonium nitrogen sulfate. By multiplying the measured nitrogen content by a specific coefficient, the protein content can be determined. This method is established as the current national standard for determining protein content in food and is internationally recognized as the standard for nitrogen determination. The kjeldahl apparatus is structured based on the principles of the Kjeldahl method for nitrogen determination, making it applicable for assessing nitrogen or protein content.
