Air separation is currently the main method for industrial production of oxygen, nitrogen, and argon. Due to air pollution, hydrocarbons contained in the raw air enter the oxygen concentrator system, directly threatening safety production, and the situation is quite serious. In recent years, there have been hundreds or thousands of explosions in large, medium, and small air separation equipment both domestically and internationally due to excessive hydrocarbon content, resulting in astonishing direct and indirect losses. If detected at any time, the content of hydrocarbons can be predicted in advance, and measures can be taken early to prevent explosions. GC-9860 typeTrace hydrocarbon chromatographBeing able to help you detect and predict in a timely manner is the best choice for air separation explosion prevention!

GC-9860 typeTrace hydrocarbon chromatographFor automatic gas chromatography, it can continuously and automatically analyze trace hydrocarbons in liquid oxygen, liquid air, and suction air in the air separation process, monitor the changes in the content of explosive components C1-C4 in real time, and provide important reference data for the safe operation of the main condenser of the air separation equipment. It can also be used as a process controller for detecting hydrocarbons in industries such as petrochemicals, steel, and gas.
　

Function and Features:

1. Automatic sampling, injection, and output analysis report. Automatic detection of liquid air/liquid oxygen/product oxygen three-way circulation, or single channel detection, with unmanned operation during automatic mode. 24-hour continuous online work.

2. The chromatographic column has a long service life and short analysis time, less than 5 minutes.

3. The detector has high sensitivity and low noise. Acetylene detection concentration is 0.02ppm.

4. Choose between two detection components (four components and nine components).

5. The automatic prototype valve has a novel structure, long service life, and can work continuously up to 100000 times without damage.
