Argon Supply
Make sure that an adequate supply of argon is available and connected to the system.
Check that the argon tank(s) have sufficient pressure, and that a spare tank is ready
if necessary. Argon can be purchased from local suppliers. The argon for use with
ICP systems should be 99.996% pure.
Argon output pressure: 550-825 kPa (80-120 psig)
Purge Gas Supply
The optical path must be purged with either nitrogen or argon. Nitrogen is the
recommended purge gas due to its lower cost. Make sure that an adequate supply of
purge gas is available and connected to the system. Check that the cylinder has
sufficient pressure, and that a spare cylinder is ready if necessary.
The purge gas should be 99.999% pure and is available from local suppliers.
Nitrogen output pressure: 275-825 kPa (40-120 psig)
Shear Gas Supply
The Avio 200 requires a supply of shear gas. The shear gas used is typically
compressed air; however, nitrogen may also be used. Make sure that an adequate
supply of shear gas is available and connected to the system. Check that the supply
has sufficient pressure, and that a spare cylinder is ready if necessary.
Shear Gas output pressure: 550-825 kPa (80-120 psig)
Chiller
Fill the reservoir up with the coolant fluid with inhibitor (Part No. N0776200). The
chiller reservoir has a capacity of 4.2 liters (1.1 US gallons).
Cooling water pressure: 310-550 kPa (3.1 to 5.5 bar or 45-80 psig)
Vent
Check that your vent system is switched on and is not blocked. Check regularly for
proper flow rate of the vent system (120 CFM/min).
