Q150T Sample Preparation SystemQ150T - Instruction Manual 13 10473 - Issue 52.3.1 Gas Connections1. Connect a suitable argon supply at a regulated input of 0.3bar (4psi) to the quickconnect Argon gas connector on the rear panel (see Figure 2-1. If you prefer, youcan use argon for both process and purge supplies.(recommended if coating withoxidising targets). To do so, install a 'T' piece across both gas inlets.2. Connect a suitable nitrogen supply at a regulated input of 0.3bar (4psi) to thequick connect Nitrogen connector on the rear panel. Air may be used in place ofnitrogen for venting (not recommended for oxidising targets) but it is important tofit the filter (part no. 12842) to prevent ingress of dust (see Figure 2-2). Failure toconnect this filter could prevent the system venting at the end of a cycle.Connectors are push-fit and will 'snap' into a locked position. To release a connector,depress the metal tongue.Figure 2-2. Gas connectors with filter (part no. 12842) fitted to purge gas inlet
