workstation (if the user has appropriate privilege
assignment). In order for sequence changes to take effect, the
sequence must be saved (File>Sequence>Save). When the
sequence is saved, all other clients will be notified of the
change, and the next run of the sequence will be executed
from the modified sequence.
Closing a Server Instrument
Once an instrument application is started on an Agilent
Instrument Controller, it will remain open after all runs are
completed. Occasionally, it may be necessary to close a server
instrument (for example, to re-configure). Users with
Instrument Administration privileges can close a server
instrument by doing a right-hand mouse click on the
instrument icon in the CS Main window, then selecting the
Close Server… command. You will be prompted to confirm
your choice.
If you select Yes, the command will force the server
instrument to close after it finishes the runs and all clients
have been disconnected.

About Method Files
A method is used whenever you acquire and/or reprocess a
data file. It contains instructions for data acquisition (run
time, sampling rate, etc.), integration, calibration and peak
information, and reports, as well as optional functions such
as data export and user programs. Each method is capable of
acquiring multiple independent channels of data from a single
chromatograph. Each channel can have its own complete
independent parameters, including sampling rate, run time,
integration events, external events, calibration, and reporting.
Although the method file is a separate file, the information
contained in the method is saved in the raw data file at time
of acquisition. This way, the original method can be
reproduced, even if the method file was subsequently
modified.
