To Create or Edit a Sleep, Wake, or Condition Method
To create or edit a SLEEP, WAKE, or CONDITION method:
1 If desired, load a method with similar setpoints.
2 Edit the method setpoints. The GC allows for setting only
relevant parameters:
• For a SLEEP method, the GC sets the initial oven
temperature, inlet and detector temperatures, inlet
(column) and detector flow rates, auxiliary
temperatures, and so forth. The GC ignores any ramps
in a SLEEP method, as well as signal output, or other
run- related or time- related settings. The SLEEP method
cannot be run.
• For a WAKE method, the GC can set the same
parameters as for the sleep method. The GC ignores
any ramps in a WAKE method, as well as signal output
or other run- related or time- related settings. The WAKE
method cannot be run.
• For a CONDITION method, the method can also include
ramps, for example an oven ramp. The oven run time
sets the length of time the CONDITION method setpoints
apply to the GC before the GC loads the wake method
or last active method. While the GC runs the
CONDITION method to apply any ramps and hold times,
the GC does not collect data or produce a signal. The
CONDITION run is a blank run—there is no injection.
3 Press [Method], scroll to the method to store (SLEEP,
WAKE, or CONDITION), and press [Store].
4 If prompted to overwrite, press [On/Yes] to overwrite the
existing method or [Off/No] to cancel.
