Briefly on the precautions for the use of Laboratory nitrogen gas generator

　　The laboratory nitrogen generator uses advanced materials and gas chromatography separation technology to directly extract high-purity nitrogen from the air. The gas supplied by the air compressor is guided to the stationary phase. Oxygen, carbon dioxide, water and other impurities are removed through the stationary phase. Only nitrogen is allowed to pass through the stationary phase and enter the gas storage tank. After adjusting the appropriate pressure and flow rate in the gas storage tank It can be used directly, the stationary phase column adopts an automatic reproducible device, and the stationary phase does not need to be replaced.It is a purely physical separation method that completely eliminates the hidden dangers of electrochemical separation to corrode the instrument. It is a generator that replaces traditional electrolyte chemical separation to obtain nitrogen. It has the advantages of safe use, reliable performance, and long life. It can provide carrier gas for various types of gas chromatographs at home and abroad. It is a generator that replaces traditional electrolyte chemical separation of nitrogen.
　　The following is an introduction to the use of Laboratory nitrogen gas generator:
　　1. The instrument must be placed steadily and never tilted. The instrument has been debugged before leaving the factory, and the user only needs to connect the outlet port to the instrument used.
　　2. Pay attention to the nitrogen pressure gauge, the pressure should not exceed 0.4Mpa, the output nitrogen pressure of this instrument is 0.4Mpa.
　　3. Pay attention to the air pressure gauge, the pressure should be maintained at 0.7Mpa, if the display is not 0.7Mpa, please adjust the air regulator valve, such as nitrogen regulator valve. Otherwise, the air regulator valve must not be adjusted casually.
　　4. The sponge filter pad of the air inlet is recommended to be cleaned every 4 months.
　　5. During use, a certain amount of condensed water will accumulate in the high-pressure storage tank. It is recommended to drain once a week. The operation method is: hold the drain hose nozzle to the ground and press the drain switch on the front panel to drain.
　　6. Do not open the external air purifier cover under pressure. The method of air emptying is: the power switch is in the off state, the drain hose nozzle is held to the ground, and the water drain switch on the front panel is pressed while observing the air pressure gauge, indicating that 0Mpa is emptying. Replace or regenerate the adsorbent in the external purifier every 300 hours of work. This adsorbent is activated carbon and cannot be changed to another type of adsorbent. To ensure the service life of the instrument, please strictly follow this operation.
