QuickSwap Installation and Startup
Overview
1. Confirm that the GC and MSD are Ready for QuickSwap
1
Install the GC and the MSD on the laboratory bench and verify
performance, as described in their respective manuals.
2
Confirm that the GC has a pressure-regulated inert purge gas (such as
helium, nitrogen or argon) source for QuickSwap, either a G1570A/G3349B
Auxiliary EPC (6890/6850 GC) or G2317A PCM (6890 GC).
If you are using an Auxiliary EPC for the purge gas, confirm that it reads
0 (zero) pressure when it is off and the output line is not connected. If it
does not, perform the following steps to zero it. The steps are written for a
6890 GC; the 6850 procedure is similar but requires the hand-held
controller.

to zero the sensor.
3
Confirm that a purge gas line runs from the pressure-regulator module into
the left part of the GC oven. The line terminates in a 1/16-inch Swagelok
fitting. (For new GCs ordered with GC Option 885, Agilent installed this line
at the factory.) See
4
Inspect the GC end of the transfer line. Ensure that there is no particulate
matter stuck to the surface and that there are no scratches that run across
the surface (these can be the source of gas leaks and would require
excessive tightening of QuickSwap).
WA R N I N G
Do not use hydrogen or any other flammable gas as the purge gas, regardless of the
carrier gas choice.
