Gas Usage Precautions
The following information explains important points concerning the handling of high-pressure gas. Be sure to
read all information carefully and follow all instructions.
For information on gas types, purity, and supply pressures, refer to the GC Instruction Manual [2.6 Gas supply
plumbing].
When handling high-pressure gas cylinders:
• Be sure to install gas cylinders in a well-ventilated outdoor area, away from direct sunlight. Use tubing to
bring the gases to the lab.
• DO NOT allow the temperature of the gas cylinders to exceed 40°C. Keep all flammable items at least
2 m away from gas cylinders.
• Be sure the work area is well ventilated when using high-pressure gases. Perform a daily leak check
before starting operation using soapy water, etc.
• When using flammable gases (e.g. hydrogen), DO NOT smoke or use fire within 5 m of the instrument.
Locate fire extinguishers nearby for use in case of accident.
• Be sure to secure gas cylinders in place with cylinder clamps or ropes to prevent them from falling over.
• Be sure to use only oil-free reducing valves. DO NOT use pipes that have oil on the inner surface.
• Be sure to close the main valve of a gas cylinder immediately after using that gas.
Be sure to observe all laws and regulations in your country.
WARNING

Risk of explosion.
If hydrogen accumulates in the column oven, it could cause an explosion.

the valve OFF and cover the column mounting port with a sealing plug.
