The FX-K55 fully automatic Kjeldahl nitrogen analyzer uses a 32-bit microcomputer intelligent control, LCD color touch screen operation, and automatically completes a series of processes such as adding sulfuric acid, alkali, diluent, distillation, titration, cleaning, storage, printing, etc. By using the three primary color method for judgment, the data is accurate and the performance is stable.
1. Measurement range: 0.01-210mg nitrogen
2. Distillation time and capacity: 0-9 minutes per sample, 0-30ml/minute adjustable
3. Standard acid concentration range: 0.01-0.4mol/L standard acid.
Titration accuracy: ≤ 0.0012 μ L/step, small titration volume: 0.8ul/step, resolution: 3ugN
4. Reproducibility: RSD ≤ 0.5%
5. Recovery rate:>99.5% (can be used as an acceptance indicator)
6. Linear range: Within the range of 1-4 times the sample size of the same sample, RSD<1.2%, (nitrogen content 3-210mgN)
7. Reagent pump volume: 0-150ml, 1ml/level
8. Delay time: 0-3600s (suitable for detecting nitrate nitrogen)
9. Distillation power: 0-1500W adjustable
10. Power supply: AC220V ± 10%, frequency 50-60Hz, power 1500W
1. Provide prompts on ammonia distillation condition, whether the titration endpoint is at the acid-base equilibrium point, and the correctness of the data.
2. It has independent sample and quality control sample storage areas, and quality control samples are automatically generated into quality control maps.
3. It is possible to search for historical samples, quality control data, detection status, and whether ammonia gas is distilled as a reminder. With 100 samples per day, 250 days per year, it can store data for 8 years.
4. Wide application of standard acid, which can use 0.01-0.4mol/L standard acid, greatly expanding the detection range. Small titration volume 0.8 μ Starting from l, the instrument automatically adjusts the small titration volume based on the standard acid concentration.
5. The standard acid drop is quantified from 0ml-60ml, which is not limited by the volume of burette.
6. Equipped with various safety door detection, reagent level detection, digestion tube in place detection, automatic discharge of waste liquid from digestion tubes and reaction cups, automatic real-time detection of cooling water flow and water pressure, and automatic shutdown of condensate water when the instrument is waiting.
7. It has real-time temperature detection and control for the distillation cup;
8. Manual and automatic dual mode, convenient for special sample detection.
9. Intermittent alkali addition ensures that the acid-base reaction is in a controllable state, avoiding the intense acid-base reaction generating heat and causing ammonia gas to escape in the absence of steam.
10. Adjustable distillation power: Distillation within the 0-power range, meeting the special testing requirements of users.
11. The internal connecting pipelines of the instrument are customized by Hergren and are free of replacement for 3 years.
12. Various reagents are measured and added with a liquid pump, measured in ml.
13. Titration and distillation should be carried out simultaneously to avoid the problem of excessive titration.
14. The reaction cup is external and not affected by external light sources.
15. The data and detection conditions are traceable and can store unlimited pieces of data, meeting the requirements for data storage within the effective life of the instrument. The USB interface can be connected to a computer for further data processing.
16. For each quality control data storage, you can choose to print quality control charts, samples, and quality control data.
