The fully automatic Kjeldahl nitrogen analyzer (protein detection) is an automatic intelligent detection instrument designed based on the classic Kjeldahl nitrogen determination principle. It is widely used to detect the total content of ammonia nitrogen and protein nitrogen in grain, oil, food, dairy products, beverages, feed, soil, chemical fertilizers, medicine, sediments, and chemical products. It is an important physicochemical analysis instrument for product quality detection. - Nitrogen analyzer manufacturer
I. Scope of application and overview
The fully automatic Kjeldahl nitrogen analyzer uses a new long-life design, intelligent microcomputer control, and a color LCD touch screen operation. It automatically completes a series of standardized processes, including adding acid, adding alkali, adding diluent, distillation, titration, cleaning, storage, and printing. With an optional 20/40-position automatic sampler, it achieves unattended fully automatic analysis. Equipped with a refrigeration system, it does not consume tap water. Titration uses the internationally standardized colorimetric method (color sensor). This instrument is easy to operate, with accurate data and stable performance.
II. Product features
1. Main uses: Detecting the content of protein and nitrogen elements in various samples.
2. Adopts the national standard Kjeldahl nitrogen determination method: sample digestion in a concentrated sulfuric acid environment, alkaline steam distillation, boric acid absorption, and indicator titration endpoint color determination method. The fully automatic nitrogen analyzer has quantitative automatic dilution, alkali addition, delayed distillation, automatic addition of receiving liquid, distillation, built-in automatic titration, and digestion tube
3. Functions for emptying and recording titration results.
4. Uses a 10-inch color touch display system for equipment control and data processing.
5. Titration speed can be set arbitrarily from 0.05ml/s to 1.0ml/s; the minimum titration volume can reach 0.2μl/step; the fastest titration speed is 40ml/min.
6. A 25mL syringe and a 0.6mm pitch linear motor form a high-precision titration system with high accuracy and good stability.
7. Distillation mode: Dual distillation mode, steam output flow rate and distillation time are adjustable, distillation time can be set freely from 0 seconds to 6000 seconds.
8. The instrument has a built-in protein coefficient lookup table for users to consult, query, and participate in system calculation functions.
9. Features simultaneous distillation and titration and variable speed and volume titration technology to reduce testing time and improve testing accuracy;
10. The splash-proof bottle is made of high-molecular material resistant to alkali corrosion;
11. PID regulated steam system provides stable steam flow to ensure effective sample separation and system **.
12. Host storage program: Stores multiple main programs, calibration data, and test results. 99 sets of user-defined program (formula) management system. Data storage capacity: Can store 1 million sample data for users to view.
13. Uses metal condensation, with the temperature sensor placed at the outlet of the cooling water in the condenser, directly monitoring the temperature of the distillate to ensure that the temperature of the distillate does not exceed the limit, ensuring the accuracy of the test results.
14. **Monitoring function:** Door, digestion tube not in place alarm, steam generator has pressure sensor, temperature sensor, temperature protection switch, liquid level
15. Monitoring, real-time monitoring of cooling water flow, and multiple protections.
16. Built-in positive pressure titration system.
17. Features steam balance added distillation mode and delayed distillation mode; segmented alkali addition, automatic, 5-second interval; adjustable delayed distillation mode time (Delay): 0-9999 seconds.
18. Built-in maintenance reminders and maintenance operation guide.
19. Data interfaces: USB, LAN, RS232, CAN, WIFI, Ethernet, refrigeration system, reagent tank level sensor, etc., are available for users to choose.
20. Optional: Connect to the LIMS system, reserved TCP/IP protocol interface for easy Lims system acquisition of instrument output data in various formats such as PDF, Excel, and Txt;
21. Optional: Computer control of the fully automatic nitrogen analyzer host, and experimental results data are directly saved to the computer.
22. Optional: 20-position/40-position fully automatic sampling system, 300ml digestion tube for the sampler.
23. Optional: High-efficiency cooling water circulation system, controlled by the nitrogen analyzer host, energy-saving, environmentally friendly, and stable.
