4 Installing 7890 GC Columns
The GC/MSD Interface for a 7890B Series GC
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, spring, and knurled tip
seal retainer interfere with, and must be removed when using the EI SS and Inert
sources.

The GC/MSD interface operates at high temperatures. If you touch it when it is
WAR N IN G
hot, it will burn you.
