SDCHNS536 hydrocarbon nitrogen and sulfur element analyzer
Introduction: SDCHNS536 hydrocarbon nitrogen and sulfur element analyzer is mainly suitable for measuring carbon, hydrogen, nitrogen and sulfur in samples in the fields of electric power, coal, metallurgy, petrochemical, coal chemical, environmental protection, cement, papermaking, geological prospecting, scientific research institutes, solid/hazardous waste, etc. And other element content. Comply with the standard GB/T30733-2014 "Instrumental method for the determination of carbon, hydrogen and nitrogen in coal" ASTM D5373-08 "Instrumental method for the determination of carbon, hydrogen and nitrogen in laboratory samples of coal" ISO 19579:2006 "Solid mineral fuels- Determination of Sulfur Content by Infrared Spectroscopy" GB/T25214-2010 "Determination of Total Sulfur in Coal by Infrared Spectroscopy" ASTM D4239-2012 "Determination Method of Sulfur in Coal and Coke Analysis Samples (High Temperature Tube Furnace Combustion Method)" Features: 1. Powerful and cost-effective. a. 1 set of equipment can not only complete all the tests of the four elements of CHNS, but also support individual tests of a single element or multiple elements; b. CHN element testing is integrated with automatic sample delivery, experiment, and cyclic testing, which can be completely unattended. 36 samples can be placed in a single disc at a time, 72 samples can be placed in a double disc, and samples can be added/replaced during analysis; c. S element test is fast and manual sampling, easy to operate, without complicated mechanical actions. 2. The whole process is controlled, and the test results are highly accurate. a The sampling component adopts a gas wall protection mechanism, which can effectively isolate the outside air from entering the combustion furnace when the sample falls. At the same time, it is supplemented by a flow-sharing mechanism to ensure sufficient sample combustion, avoid sample splashing during sample drop, and ensure accurate experimental results; b. Use high-performance, high-precision infrared sensors to test carbon and hydrogen elements, and can monitor the combustion situation in real time, accurately judge the end of the combustion, effectively shorten the test time and improve the test accuracy; c. Adopt the diffusion type thermal conductivity cell with high sensitivity and ultra-low temperature drift, independent and precise temperature control, to ensure the stable thermal conductivity baseline; 5. Ultra-low drift infrared pool, only one drift correction in a working day can meet the requirements. 3. The gas path is short and reliable. Using manifold integrated gas circuit, low dead volume, less pipeline, less water vapor residue, automatic and precise control of flow, high reliability of the gas circuit. 4. Humanized design, convenient operation. a. The air tightness test of the instrument can be automatically completed by mouse operation, which is simple and convenient; b. The crucible can be replaced from the top, the furnace body is easy to disassemble and assemble, and the furnace reagent is easy to replace; c. Optional high-performance touch panel computer, with multi-functional rotating telescopic stand, telescopic folding, free distance and near, giving you a completely new operating experience. 5. Low test usage cost. The sensor has a short stabilization time and high stability. During the experiment, a helium throttling device was added, and a large flow of helium of 0.7L/min was turned on only during the sample injection test, and the helium flow was only 0.05L/min in other periods. Compared with similar instruments, the utilization rate is greatly improved, effectively saving users' use costs. technical parameter: Test range: carbon (0.005%~100%) hydrogen (0.01%~50%) nitrogen (0.01%~50%) sulfur (0.01%~50%) Number of samples: Hydrocarbon and nitrogen: 36/72 (samples can be added/replaced during analysis) Sulfur: 1 Analysis time: ≤5min/piece Sample mass: hydrocarbon nitrogen: 75mg~105mg (recommended mass: 100mg) Sulfur: 100mg~300mg (recommended mass: 100mg) Maximum power: 8.5kW Power supply voltage: 220V±10%, 50/60Hz Repeatability: carbon≤0.5% hydrogen≤0.15% nitrogen≤0.08% sulfur: St,ad≤0.05% (St,d≤1.5%) St,ad≤0.1%(1.50%＜St,d≤4%) St, ad≤0.2% (St,d>4%) Combustion gas: oxygen Driving gas: nitrogen Carrier gas: helium
