Loading A Method; Run Control Features - Agilent Technologies 6850 Series II User Information

The active method
The active method is the method the GC is currently using. To use a different
method, you must load it. When a different method is loaded, the GC
components immediately begin changing to the set of control values specified
in the new method.
If you modify a method after loading it, the display will show a + symbol after
its name. For example, Default+ means you made changes to the Default
method. Use the Control Module or ChemStation/Cerity Chemical to save the
changes, if desired.

Loading a method

To load an existing method:
1.
2.
3.
Allow a few seconds for the method to load completely. The Not Ready light
comes on and remains on until the GC has stabilized. Stabilization time
depends on how much the new and old setpoints differ.

Run control features

Gases
The GC automatically controls all gas pressures, adjusting for temperature and
for any programs in your method.
Use a Control Module or ChemStation/Cerity Chemical to enter inlet, column,
and detector gas stream settings as pressures or as flow rates. To use inlet and
column flow rates, you must define the column by entering its dimensions (see
your Control Module or ChemStation/Cerity Chemical documentation for
details). We strongly recommend that you define your columns to take
advantage of the GC's flow control capability.
