Coal Testing Equipment CHN Analyzer : Carbon Hydrogen Nitrogen Analyzer CHN001

Carbon, Hydrogen and Nitrogen Analyzer is a precision analytical instrument built by Advance Reasearch Instruments Company is based on years of technical accumulation and according to user needs. It can accurately determine the content of carbon, hydrogen and nitrogen in coal. It adopts a horizontal structure according to the customer's existing laboratory conditions. The instrument can be placed on the experimental table for experiments, which is convenient for customers to add samples and test. Suitable for power plants, coal mines, commodity inspection, environmental protection, geological prospecting, metallurgy, papermaking, chemical industry, scientific research, education and other departments to determine the content of carbon, hydrogen and nitrogen elements in solid substances such as coal and coke. Technical Parameters Measuring range: carbon: 0.005% to 100%, hydrogen: 0.01% to 60%, nitrogen: 0.008% to 60% Repeatability: Carbon (Cad≤0.5%), Hydrogen (Had≤0.15%), Nitrogen (Nad≤0.08%) Temperature control range: RT+10～1050℃ Temperature control accuracy: ±1°C Sample quality: recommended 80 ~ 100mg Sample delivery method: automatic sample delivery, automatic sample drop Quantity of samples: 39 pieces/batch, samples can be added/replaced during the test, and 78 sample trays can be purchased at one time Single sample analysis time: about 4 minutes Carrier gas: helium, purity ≥99.995%, pressure 0.25±0.1MPa Supporting gas: Oxygen, purity ≥ 99.5% when measuring hydrocarbon elements, When measuring nitrogen, the purity is ≥99.995%, and the pressure is 0.25±0.1MPa Power gas: inert gas, oil-free and water-free, pressure 0.29±0.1MPa Power: ≤4.5kw Placement method: horizontal (can be placed on the experimental table) Dimensions (mm): 690×740×720 Machine quality (kg): 105 Technical features 39 samples can be staked out at one time, and a sample plate with 78 samples can be purchased at one time. The instrument can automatically send samples, drop samples, and cycle test. With horizontal structure, the instrument can be placed on the laboratory table, which is convenient for customers to operate Using advanced PID algorithm for temperature control, the temperature control accuracy of the furnace can reach ±1°C, and the temperature control accuracy of the constant temperature chamber and gas storage tank can reach ±0.1°C; The absolute pressure sensor is used to monitor the pressure of the entire gas circuit of the instrument, and the air tightness of the entire gas circuit, furnace, infrared pool, thermal conductivity pool, and gas storage tank can be automatically tested; The instrument adopts infrared spectrum absorption method to measure carbon content and hydrogen content, and uses thermal conductivity method to measure nitrogen content; The test speed is fast and the degree of automation is high. The test time for carbon, hydrogen and nitrogen is about 4 minutes. During the experiment, you can choose the option of "automatically cool down after the experiment is completed". After the experiment is completed, the computer will automatically shut down and the instrument will automatically cool down. It can be unattended and does not require personnel to manually cool down and shut down after the test; Experimental reports can be written according to customer requirements, reducing the workload of customers It can be connected to the laboratory management system, so that the balance data does not fall to the ground, and the test results are backed up and uploaded.
