2 Installing 7890 GC Columns
The GC/MSD interface is heated by an electric cartridge heater. Normally, the
heater is powered and controlled by Thermal Aux #2 heated zone of the GC.
The interface temperature can be set from Agilent MassHunter GC/MS
Acquisition software or from the GC. A thermocouple sensor in the interface
monitors the temperature.
The GC/MSD interface should be operated in the range of 250  to 350 C. The
interface temperature should be slightly higher than the maximum GC oven
temperature, but never higher than the maximum column temperature.
The GC/MSD interface can be used with both EI and CI sources. The EI XTR,
HES, and CI sources require a tip seal assembly. The tip seal and spring
interfere with, and must be removed when using the EI SS and Inert sources.
