ONH-7100 Oxygen, nitrogen, hydrogen Analyzer Introduction:
Oxygen and hydrogen: measured by infrared absorption method, the sample is heated and melted in a graphite crucible in the presence of an inert gas flow, in which the temperature of the pulse furnace can be freely set to complete the decomposition of the sample, and the generated CO and H2 are converted into CO2 and H2O are brought into a long-term stable CO2 infrared detector and H2O infrared detector with high stability and sensitivity. Nitrogen is measured using a thermal conductivity detector. Features:
1. Fast and accurate analysis, automatic operation;
2. One-time analysis of three elements of oxygen, nitrogen, and hydrogen
3. Oxygen dual-range automatic switching of high and low content;
4. High-resolution and reproducible N-thermal cell detector and CO2 for oxygen measurement and infrared detector for H;
5. The same instrument can simultaneously achieve the fusion extraction of three elements of oxygen, nitrogen, and hydrogen;
6. The electrode adopts high-temperature alloy material can freely choose the temperature up to 3000 °C;
7. Gradient rise, linear temperature rise, step-up temperature, constant power and other ways.
8. Suitable for analysis of samples of different materials.
9. Automatic blanking burner device with air curtain protection;
10. With automatic purging mechanism;
11. The upper and lower electrodes are easy to dismantle and easy to replace;
12. Peripheral computer for operation and control;
13. The main functions of the software:
14. Quickly display the analysis results and analysis curves;
15. The analysis results are automatically stored;
16. The sample weight is automatically input;
17. Real-time monitoring of instrument parameters;
18. Automatic alarm when an error occurs
19. Dynamic release curve drawing and storage, uninstall;
20. Analyze the results Multiple correction modes can be manually corrected or corrected by the results of the analysis; single-point corrections can be performed, or multiple-point corrections can be performed;
21. Screening data, averaging, standard deviation, relative deviation, etc.;
22. The user can store several analysis methods for different analysis samples.
