Introduction: The automatic Kjeldahl nitrogen analyzer adopts the international Kjeldahl method for automatic distillation of nitrogen-containing samples. Let experimenters easily complete the detection of samples in minutes. Automatic quantitative addition of required reagents, unattended in the whole process, and intelligent detection of various states. The automatic distillation, automatic condensation and automatic rinsing system further improve the measurement accuracy. It can realize the automatic drainage and cleaning function of the digestion tube, and easily complete the automatic waste drainage and automatic cleaning of the titration cup. The newly designed steam generation system can control the amount of steam and conduct real-time detection of the temperature of the receiving liquid; the highly corrosion-resistant dosing pump and Linear motor micro-control titration system ensures real accuracy of test results. Fully intelligent software design, friendly interface, rich display information, so that users can easily master the use of the instrument. It is widely used in nitrogen or protein determination in food processing, feed production, tobacco, animal husbandry, soil and fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision and other fields. It has leading technological advantages in similar products at home and abroad. Features: 1. Automatic alkali addition and acid addition, automatic distillation, automatic dilution, automatic titration, automatic waste discharge, automatic cleaning, automatic calibration, automatic digestion tube emptying, automatic fault detection, automatic Solution level monitoring, automatic over-temperature monitoring, automatic calculation results; 2. The new arm control system is fast, stable and reliable, with a large LCD full-color touch screen, built-in micro-printer, powerful functions, easy to use, and real-time control of the entire experimental process. 3. Humanizedly classify the sample detection, and embed the conventional experimental detection methods and parameters, and the experimental process can be directly called 4. The manual and automatic dual modes can be switched at will, and the whole test process is displayed in real time, which can judge whether the ammonia gas is completely distilled and the correctness of the data. 5. Use stable and reliable red, green and blue primary colors to judge, and display the measurement curve in real time. Help users monitor distillation, calculation, and titration processes in real time, replace the traditional electrode potential method and single-wavelength colorimetric method, and avoid the cumbersome process of frequent electrode replacement and calibration. 6. The titration image is displayed in real time, the entire experimental process is monitored online, and the experimental method can be adjusted in real time to improve the test accuracy and efficiency 7. Intermittent alkali addition ensures that the acid-base reaction is in a controllable state and avoids the violent reaction of acid and alkali in the absence of steam to generate heat and cause ammonia gas to escape 8. The internal pipeline of the instrument adopts self-developed anti-corrosion pipeline to ensure long-term stable use 9. All kinds of reagents are metered by liquid pump and measured in ml 10. Automatic detection of condensate water flow and water pressure, prompt for lack of alkali, boric acid, diluent, and distilled water; with condensate water cut-off sample protection function 11. The new condensing device saves 50% of water, monitors the temperature of the condensed water effluent in real time, ensures complete condensation of the sample, ensures accurate experimental results, and reduces the cost of use 12. With double distillation mode, you can choose constant continuous distillation or delayed distillation to meet the needs of different experiments 13. It can realize titration while distilling, neutralize the evaporated ammonia in time, avoid the escape of ammonia and reduce the detection time at the same time 14. With variable speed titration function, it can meet different experimental requirements and ease the intensity of acid-base reaction 15. The distillation time can be set arbitrarily, and the instrument will alarm after the distillation is over. 16. The distiller adopts double liquid level control (double insurance) to prevent dry burning in the still 17. Real uninterrupted distillation: constant steam, uninterrupted steam during make-up time. Ensure the smooth evaporation of ammonia 18. The steam flow is adjustable, making the experiment more convenient and flexible, which can ensure the recovery rate of low-concentration samples Technical parameter: Measurement range: 0.1-240mg nitrogen (0.07cmol/KG-14mol/KG) Determination of sample weight: solid ≤ 6g, liquid ≤ 20mL Repeatability error: RSD <0.5% (10-150mgN), RSD <1.0% (3-10mgN) RSD <1.5% (1-3mgN) Linear range: the sample in the digestive tube is in the range of 1-3 times nitrogen content, RSD<1.5% (nitrogen content 3-150mgN) Recovery rate: >99.5% Condensation water consumption: 1.5L/min Distillation capacity: 15~30ml/min adjustable Distillation delay: 0-1800s (easy to detect nitrate nitrogen) Pump titration accuracy: RSD <0.002ul/step Minimum titration volume: 0.9ul/step Standard acid titration volume: unlimited Power supply: AC220V±10%, frequency 50-60HZ
