2.5.2 Argon gas
Use an argon gas cylinder to supply argon gas. Only a trace amount of argon gas is used (maximum
consumption 5mL/min). As an approximate standard, and assuming a 3L cylinder with a maximum flow
rate, a single cylinder will last for approximately 2 months. Gas pressure may be smaller than expected if
gas supply pipings are long. Please take care with gas supply piping length and pipe inner diameter as
this may prevent normal control of the gas.
Prepare the following pressure regulator and pipes given below, or equivalent products, if using an argon
gas cylinder.

2.5.3 General precautions
Take care when supplying gas by centered gas supply as other instruments being used may be
affected by the amount of gas supplied.
If using a cylinder, please use 5m or shorter pipes in general carrier gas piping. If gas supply lines are
long, the prescribed gas pressure may not be supplied to the iMScope TRIO due to pipe resistance. It
is furthermore necessary to raise the cylinder’s secondary pressure higher than the prescribed
pressure so as to ensure prescribed pressure for the iMScope TRIO.
2.5.4 Precautions when using high pressure gas cylinder
General precautions when using gas cylinders
１．
Install the gas cylinder in a well-ventilated area outside the room, away from direct sunlight, and use
piping to run the gas into the room.
２．
Never allow the gas cylinder to reach 40 °C or a higher temperature.
Additionally, ensure that there
are no open flames within 2 m of the gas
cylinder.
３．
When using high pressure gas pay sufficient attention to ventilation and use soapy water or other
methods to check for leaks before starting work. When using flammable gases, in particular, do not
smoke or allow open flames within 5m of the equipment that uses the gas. Have a usable fire
extinguisher ready.
４．
Secure the gas cylinder with means such as a rope so that it does not topple or fall.
５．
Use oil-less pressure release valve. Do not use valves that oil has adhered to within piping that comes
into contact with gas, or in other areas.
６．
Immediately shut off cylinder source valve when finished using gas.
