Keypad Operation 3
Operation Manual 25
The GC Component Keys
These keys are used to set the temperature, pressure, flow,
velocity, and other method operating parameters.
To display the current settings, press any one of these keys.
More than three lines of information may be available. Use
the scroll keys to view additional lines, if necessary.
To change settings, scroll to the line of interest, enter the
change, and press [Enter].
For context- sensitive help, press [Info]. For example, if you
press [Info] on a setpoint entry, the help provided would be
similar to: Enter a value between 0 and 350.
[Oven] Sets oven temperatures, both isothermal
and temperature programmed.
[Front Inlet]
[Back Inlet]
Controls inlet operating parameters.
[Col 1]
[Col 2]
[Aux Col #]
Controls column pressure, flow, or
velocity. Can set pressure or flow ramps.
[Front Det]
[Back Det]
[Aux Det #]
Controls detector operating parameters. If
configured with a 5977 MS, control GC- MS
communications and special functions.
[Analog Out 1]
[Analog Out 2]
Assigns a signal to the analog output. The
analog output is located on the back of
the GC.
[Front Injector]
[Back Injector]
Edits injector control parameters such as
injection volumes and sample and solvent
washes.
[Valve #] Allows control of a sampling valve and/or
switching valves 1 to 8 (on or off). Sets
multiposition valve position.
[Aux Temp #] Controls extra temperature zones such as
a heated valve box, a mass selective
detector (or other) transfer line, or an
“unknown” device. Can be used for
temperature programming.
[Aux EPC #] Provides auxiliary pneumatics to an inlet,
detector, capillary flow technology (CFT)
device, or other device. Can be used for
pressure programming.
[Column Comp] Creates a column compensation profile.
