CHN Elemental Analyser LCHN3600
The LCHNS 3600 CHN Elemental Analyser is a highly accurate and fully automated solution for the determination of Carbon, Hydrogen, and Nitrogen in solid and combustible samples. Equipped with a 30-position sample autoloader, it enables unattended operation and high-throughput analysis with excellent precision and repeatability. Using advanced infrared absorption and thermal conductivity detection technologies, the analyser delivers reliable CHN results across applications such as coal, coke, biomass fuels, ash, plant materials, petroleum products, and industrial wastes.
-
Autoloader with 30 positions, Samples can be added or replaced in the process of testing.
-
Automatic sample introduction and testing, realize to work unattended.
-
Short Thermostatic Time and High-Test Efficiency
-
Independent and accurate thermostatic control for analyser and sensor unit, thermostatic time only need 90 minutes.
-
High Precision Sample introduction component adopted air curtain design; it can prevent the air into the furnace. and auxiliary by flow equalize unit, guarantee the sample combustion completed, avoid sample splashing when drop, ensure the test result is accurate.
-
Adopted high-performance and precision IR sensor to testing the carbon and hydrogen element, and monitoring the combustion situation in real time, competently assess the combustion completion, shorten the test time and obtain a high precision test result.
-
With high sensitivity and ultra-low temperature drift diffusion type thermal conductivity cell, independent and accurate thermostatic control, ensure the thermal conductivity baseline stable.
-
Using PID temperature control, furnace temperature control accuracy can reach ± 1 °C, thermostatic chamber and air storage tank temperature control accuracy can reach ± 0.1 °C.
-
Use absolute pressure sensor for monitoring the whole gas line pressure of the instrument, automatic air tightness check to the whole gas line and furnace, infrared pool, thermal conductivity pool and air storage tank.
-
The instrument uses ultra-low drift infrared pool and thermal conductivity pool as the core component of elemental analysis, so that the experimental results are more Accurate.
-
Adopted confluence board to integrated the gas path, low dead volume, short gas path and less water vapor residue, accurate and automatic flow control, gas path reliability Improved.
-
With unique airtightness detection device, can detect the tightness of the gas line in sections under the program control, determine the failure to a specific range.Convenient for gas line maintenance.
