Ultimate Analyzer C/H/N

♦ Application 5E-CHN2000 Elemental Analyzer is used to determine Carbon, Hydrogen and Nitrogen content in coal, which is widely applied in power plant, coal mine, metallurgy, chemical industry, commercial inspection, scientific research, education etc. ♦Standard Configuration ♦Specifications Model 5E-CHN2000 Elemental Analyzer / 5E-CH2021 CH Analyzer Analysis Range C 0.005% 100% 50ppm, H 0.02% 50% 200ppm, N 0.008 50% 80ppm Analysis Time 6 7 mins Sample Wight 80-100mg recommended Accuracy Carbon(Cad)≤0.5% Hydrogen(Had) ≤ 0.15% Nitrogen(Nad) ≤ 0.08% Method C&H by IR Absorption Method, N by thermal conduction detection method Gas Required Carrier gas:Helium gas, purity 99.995%,(0.25± 0.01)Mpa, Combustion Gas: Oxygen, for measuring C&H:purity 99.50%; for measuring nitrogen, the purity of higher than 99.995%, 0.25±0.01 Mpa, Power gas: Compressed air or Nitrogen without water & oil. Furnace Type Electric resistance furnace, Maximum. Temperature 1050 °C Auto –Sampler Loading 29 samples auomaticlly Power Supply AC 220V±10%,50HZ,12A; AC150V±10% Dimensions 710mm × 690mm × 790mm ♦ Features 1 Analysis for each elemental is controlled by separate detectors. Different analysis model could be selected, such as only analysis carbon & Hydrogen model, so the analysis consumables could be saved. 2Rapid analysis. It only takes 5 minutes to obtain the result. 3Automatic sample sending device makes operation convenient and quick. 4No need to do complete analysis for all burning gas or separate gas generated by burning. Just collecting burning gas firstly then starting analysis. User’s time and cost are saved. 5Based on optimum gas circuit control, there is a controllable closed system. So the air and residual gas of combustion could be purged by oxygen. The closed system is isolated by gas proof condition to ensure no environment influence on the result. 6Sample packaged by silver paper. When burning, make coal burning environment temperature rise by radioactive silver paper, so sample can be burned fully and quickly. Crucibles are ventilate which can bear high temp. 1500°C. 7Unique design of large size crucible, the ventilation is good, each sample can be burned fully. And the change frequency of crucibles can be reduced
