The available pressure should be between 275 and 825 kPa (2.75 to 8.25 bar or 40 to
120 psig).
The purge gas should be 99.999% pure and is available from local suppliers.
Shear Gas
Air or nitrogen can be used to shear the plasma for the Avio 200. The Avio 200 RF
generator typically consumes the shear gas at a rate of 25 L/min.
The flow rate should be approximately 25 L/min (1.0 cu. ft/min).
Available pressure should be between 550 and 825 (5.5 to 8.25 bar or 80 to 120 psig).
Regulator
A pressure regulator for use with either argon or nitrogen is available from
PerkinElmer as Part No. 03030284. To connect the regulator to the instrument gas
controls, use the 1/4-in. Swagelok connector. The gas tube provided has 1/4-in.
Swagelock fittings.
Caution
Attention
Gas delivery lines from the purge gas tank should be contaminant-free and not
made of plastic. Teflon delivery lines are acceptable.
Conduites de distribution de gaz de la cuve d'argon doivent être exemptes de
contaminants et pas en matière plastique. Lignes de livraison de Téflon sont
acceptables.
