Status of Methods
selected. Changes to this method (for example, timed integrations events)
are specific to the associated data file, and are not propagated to the
sequence method or the master method.
The navigation table offers an update possibility for individual and sequence
methods to their corresponding sequence or master method by right-mouse
click on the method line item. Executing the Update Master Method / Update
Sequence Method the data analysis parameters of the chosen method are copied
over to the corresponding Master/Sequence method. The method history of
the target method will reflect this automatic update.
Current Method
When a stored method is recalled from the disk it becomes the current
method. There is always a current method in memory. When the ChemStation
is started for the first time, the default method supplied by Agilent
Technologies is always loaded as part of the startup process. For example, this
may be one either:
• DEF_LC.M for an LC instrument
• DEF_GC.M for a GC instrument
• DEF_CE.M for a CE instrument
A copy of the default method is placed in memory and becomes the current
method. You can load a different method at this point and it will become the
current method.
