The GC/MS Interface for a 9000 GC (not to scale)
The 9000 GC/MS Tail is heated by an electric cartridge heater. The heater is
powered and controlled by a heated zone of the 9000 GC. The 9000 GC/MS Tail
temperature can be set from the Agilent MassHunter GC/MS Acquisition
software or from the GC. A sensor (thermocouple) in the interface monitors
the temperature.
The transfer line tip seal assembly is required when using the EI XTR source
or the HES.
The 9000 GC/MS Tail should be operated in the 250 to 350 C range. Subject
to that restriction, the transfer line temperature should be slightly higher than
the column temperature, but never higher than the maximum column
temperature.
