Installation
Connecting the Argon Supply
Use the following procedure to connect the argon supply.
1. Connect the instrument to the argon supply using the argon hose (Part No.
N0690274, uses a 1/4-in. Swagelok fitting) using a 3/8-in. space collar (Part
No. 09920584) on both ends of the tubing.
2. Set the argon supply regulator between 550 kPa and 825 kPa (5.5 to 8.25 bar
or 80-120 psig).
3. Check for leaks using a proprietary leak testing fluid for high purity gas lines.
Connecting the Plasma Induction Plates Cooling Gas and the Shear Gas
Supply
The flow rate should be 25 L/min (1.0 cu. ft/min).
Available pressure should be between 550-825 (5.5 to 8.25 bar or 80-120 psig).
The shear gas used is typically compressed air; however, nitrogen may also be
used. The shear gas must be clean and dry, so the instrument includes an air dryer
filter assembly (Part No. N0775325) and is included in the Installation kit (Part No.
N0770432). For more information on the requirements for the shear gas supply,
refer to
Pneumatic Requirements in the Preparing Your Laboratory, Chapter 2 .
Caution
Make sure that the required purity of the argon gas is 99.996% pure
otherwise the detector
will be damaged.
Caution
Attention
Gas delivery lines from the argon tank must be contaminant-free and not made of
plastic, although PTFE lines are acceptable.
Des lignes de distribution de gaz à partir du réservoir d'argon doit être exempt de
contaminants et non pas en matière plastique, bien que des lignées de PTFE sont
acceptables.
