1 Prepare the GC for maintenance. From the GC panel select Maintenance >
Inlets > Guard Chip > Prepare for Maintenance >Replace Liner and Guard
Chip > Start Maintenance. This procedure cools the inlet, detector, column,
Guard Chip, and other components in the flow path heated zones to < 40 °C
and configures the GC. Follow the on-screen GC prompts.
2 From MassHunter Data Acquisition, Vent the MSD (See “To Vent the
MSD” on page 109.)
3 Wait until the GC reaches the ready state indicating the components are
cooled below 40 °C and the instrument is vented before continuing the steps
in this procedure.
4 If you are using hydrogen or other flammable gas as a carrier gas or for the
JetClean system, close the manual gas supply valve to the instrument before
turning off the MSD power.
5 If installed, remove the ALS injector from the inlet.
6 Remove the inlet cover. (See Figure 12.)
7 Open the GC front door.
8 Open the bus door and remove it by lifting the door vertically off its hinge
pins.
