Coal mine specific gas chromatograph
Coal mine specific gas chromatograph
Product details
The GC-950N gas chromatograph is a specialized gas chromatograph for coal mining systems designed and manufactured by Shanghai Haixin Chromatography Instrument Co., Ltd. based on extensive consultation with experts in coal mining systems and the actual requirements of coal mining systems. Dual FID can independently measure H2, O2, N2, and CO in different channels CO2， As a result, the measurement time is greatly shortened, and the complete analysis of components can be completed within 5 minutes. The use of a four channel workstation improves the scalability of the instrument, thereby meeting the requirements of coal mining systems in terms of detection sensitivity, chromatographic peak separation, and quantitative accuracy.
Adopting a microcomputer automatic control system, with full Chinese keyboard operation and character display;
A large volume column box with an internal porous structure design ensures uniform air distribution and high temperature control accuracy, ensuring good reproducibility of analysis and achieving long-term high-temperature and near room temperature operation with its high performance;
Can measure components such as H2, O2, N2, CO, CO2, CH4, C2H2, C2H4, C2H6 in mine gas;
• File storage function for ten analysis condition parameters;
The detectors are designed with a modular approach and advanced manufacturing processes, featuring high sensitivity, low noise, and a wide linear range. Different detectors can be configured according to analysis needs;
Five level program heating function;
• Stopwatch function;
Overheating protection function for column boxes and detectors;
Advanced and unique gas path process;
☆ Three way six way valve injection is adopted, equipped with TCD, dual FID and nickel conversion furnace, to eliminate mutual interference between components and improve sensitivity and accuracy.
The determination of CO, CO2, and hydrocarbons adopts a time-sharing injection method, which avoids the insufficient detection concentration that cannot meet the safety requirements of coal mines caused by split injection. At the same time, by controlling the injection time, the total analysis time can be shortened, reducing the workload of analysts.
☆ Built in stainless steel wire mesh filter membrane, thus avoiding the problem of pipeline blockage caused by excessive coal mine gas dust.
• Minimum detection concentration • Size, weight, power supply
H2 ≤ 5ppm - Size: Width 606mm x Height 450mm x Depth 450mm
CO, CO2 ≤ 2ppm - Weight:~ 42Kg
Hydrocarbons ≤ 0.1ppm - Power supply: 220V 50HZ 2100W
