QuickSwap Installation and Startup
Plumbing the Purge Gas
Plumbing the Purge Gas
For new systems, plumbing is best done by ordering Option 885. The factory
will then make the correct purge gas line installation.
If you prefer to do the installation yourself, or if you are retrofitting
QuickSwap to an existing system, see the following instructions.
Use extreme care to avoid contaminating the purge gas line with oven
insulation during the installation.
In either case, the purge gas line must be in place before you start the
QuickSwap installation.
6850 Series II GC
To install the purge gas line:
1
Cool the GC oven and turn the power off.
2
If necessary, mount the G3349B Auxiliary EPC on the back of the GC using
the instructions provided with the kit.
3
Confirm that Channel #5 of the EPC has an output restrictor with a brown
dot or line. If not, replace it with the
FID Air flow
restrictor (part number
19231-60610) from the Aux EPC supplies kit.
4
Connect the purge gas supply and check for leaks.

Hydrogen is both a fire and explosion hazard when mixed with air. For this reason,
hydrogen must not be used as the purge gas.

Cool the column oven, inlet, and MSD transfer line before starting. They may be hot
enough to cause burns.
