HGK-55 fully automatic Kjeldahl nitrogen analyzer Introduction: The HGK-55 fully automatic Kjeldahl nitrogen analyzer is a set of automatic intelligent nitrogen or protein detection instruments designed based on the classic Kjeldahl nitrogen determination principle. It is widely used to detect the content of ammonia, nitrogen, and protein nitrogen in grains, oils, foods, dairy products, beverages, feed, soil, fertilizers, pharmaceuticals, and some chemical products. It is an important chemical analysis instrument for product quality testing. The HGK-55 fully automatic Kjeldahl nitrogen analyzer adopts a new long-life design, 32-bit microcomputer intelligent control, LCD color touch screen operation, and a Chinese menu interface to complete human-machine dialogue operation. The instrument determines the acid-base equilibrium endpoint of the reaction cup by observing the changes in the red, green, and blue primary color states. This technology is known for its stability and anti-interference ability. Can prompt to determine whether ammonia is distilled. The instrument automatically cleans and calibrates upon startup, eliminating the need for manual calibration and avoiding human inconsistency. Features: 1. Distillation titration is performed simultaneously and automatically displayed in graph form to determine whether the ammonia has been distilled and whether the titration is at equilibrium point. 2. Capable of detecting quality control samples and displaying and analyzing stored quality control charts. 3. Minimum titration volume 0.8 μ l. The instrument automatically adjusts the minimum titration volume based on the standard acid concentration. 4. The consumption standard acid titration volume range is 0ml-60ml, which is not affected by the volume range of the burette. 5. Standard acid concentration range: 0.01-0.4mol/L standard acid 6. Equipped with various safety door detection, reagent liquid level detection, automatic discharge of waste liquid from digestion tubes and reaction cups, real-time detection of cooling water flow and water pressure, automatic preheating of distillation cups, and automatic shutdown of condensate water when the instrument is idle. 7. It has real-time temperature detection and control for the reaction cup; 8. Manual and automatic dual modes, convenient for special sample detection. 9. Intermittent alkaline addition ensures that acid-base reactions are in a controllable state. 10. Adjustable distillation power: The distillation power is infinitely adjustable from 0 to 100%, meeting the special testing requirements of users. 11. The internal connecting pipelines of the instrument use pipelines with specific requirements and are free of replacement for 3 years. 12. Various reagents are measured and added using an unpressurized pump, with a volume of 1ml. 13. Titration and distillation are carried out simultaneously. 14. The reaction cup is placed externally and is not affected by external light sources. 15. The data and detection conditions are traceable and can store 200000 sets of sample data, which can meet the data storage requirements within the effective lifespan of the instrument. The USB interface can also output data. 16. Display, store, analyze quality control data, and be able to display and print current and historical quality control charts. Technical parameters: Measurement range: 0.01-240mg nitrogen Distillation time and capacity: 0.0-9.0 minutes per sample, adjustable from 0-30ml/minute Titration accuracy: ≤ 0.0012 μ L/step, minimum titration volume: 0.8ul/step Reproducibility: RSD ≤ 0.4% Recovery rate:>99.5% (can be used as an acceptance indicator) Linear range: Within the same sample size range of 1-4 times, RSD<1.0% (nitrogen content 1-240mgN, can be used as an acceptance indicator) Reagent pump volume: 0-150ml, 1ml/grade Delay time: 0-3600s (suitable for detecting nitrate nitrogen) Distillation power: 0-1500W adjustable Power supply: AC220V ± 10%, frequency 50/60Hz
