 Operation Terminology
Term Description Icon/abbr.
Status Status can be changed for each GCM.
This operation can be made by operators with use level C
or higher.
The change is possible only in the Stop mode.
Process Normal measurement, calibration and validation
Manual Manual operation
Measurement Status
of Process
It can be changed for each GCM. This operation can be
made by operators with user level B or higher.
Stream Sequence Continuously measures streams in order specifi ed in
Stream Sequence
Stream
Specifi cation
Repeats the measurement of the specifi ed stream for the
preset number of times (0: continuous, 1-999)
Calibration/
Validation
Performs calibration or validation of the specifi ed number
Operation Mode and
Command
Operation mode can be changed for each GCM or for all
GCMs at the same time.
Run Mode in which measurement is running.
Starts the measurement in the Process mode. This
operation can be made by operators with user level B or
higher.
Starts to display chromatograms in the Manual mode.
(It does not detect peaks, calculate concentration, or save
chromatograms.)
Pause Mode in which measurement pauses.
Operates until the pause time specifi ed in the GCM
method in the Process mode. This operation can be made
by operators with user level B or higher.
Stop Mode in which measurement stops.
Operates in the Process mode for the main cycle specifi ed
in the GCM method. This operation can be made by
operators with user level B or higher.
Stops the Run mode immediately in the Manual status.
Command
Cancellation
Cancels the operation mode command that is in the
operation queue in the Process mode. This operation can
be made by operators with user level B or higher.
Forced Stop Stops the current operation mode forcibly in the Process
mode. This operation can be made by operators with user
level C+ or higher.
GCM Using multiple ovens and detectors, and simultaneously
operating multiple methods, the GC8000 can measure
each component under optimum conditions. This reduces
the analysis time and achieves a fl exible confi guration that
meets customers’ needs.
A GCM is one virtual GC. When multiple GCMs are set,
the GC8000 works as much as multiple actual GCs.
Up to two GCMs can be set in an isothermal oven.
Up to two for one isothermal oven
Up to four for two isothermal ovens
Up to six for three isothermal ovens
The following settings are carried out for each GCM:
atmospheric-pressure balancing valve number, stream
valve number, stream identifi cation output, distillation
point, and peak common settings. The operations of
stream valves are set in the GCM method settings.
