SE-CHN600 Carbon Hydrogen Nitrogen Element Analyzer

Application field
Suitable for departments such as power plants, coal mines, commodity inspection, environmental protection, geological exploration, metallurgy, papermaking, chemical industry, scientific research, education, etc. to determine the content of carbon, hydrogen, and nitrogen elements in solid substances such as coal and coke.
Adopting standards
GB/T 483-2007 General Provisions for Coal Analysis Test Methods
GB/T 30733-2014 "Instrumental Method for Determination of Carbon, Hydrogen and Nitrogen in Coal"
ASTM D5373-2014 Standard Method for Instrumental Determination of Carbon, Hydrogen, and Nitrogen in Coal and Coke Laboratory Samples
Technical Features
1. 39 samples can be set out at once, and 78 sample trays can be selected for one-time setting out. The instrument can automatically send, drop, and cycle test samples. The entire process after setting out does not require manual operation, and samples can be added, removed, or replaced at any time during the analysis process;
2. Adopting a horizontal structure, the instrument can be placed on the laboratory table for easy operation by customers;
3. Adopting advanced PID algorithm for temperature control, the furnace temperature control accuracy can reach ± 1 ℃, and the temperature control accuracy of the constant temperature chamber and gas storage tank can reach ± 0.1 ℃;
4. Using an absolute pressure sensor to monitor the pressure of the entire gas path of the instrument, it can automatically perform airtightness testing on the entire gas path, as well as the furnace, infrared pool, thermal conductivity pool, and gas storage tank;
5. The instrument uses infrared spectroscopy absorption method to determine carbon and hydrogen content, and thermal conductivity method to determine nitrogen content;
6. Fast testing speed and high degree of automation, with a testing time of about 4 minutes for carbon, hydrogen, and nitrogen;
7. During the experiment, the option of "automatic cooling after experiment completion" can be selected. After the experiment is completed, the computer will automatically shut down and the instrument will automatically cool down. It can be unmanned and does not require personnel to manually cool down and shut down after the test is completed;
8. Experimental reports can be written according to customer requirements to reduce their workload;
9. Can be connected to the laboratory management system to achieve non landing of balance data, backup and upload of test results.
