4.5 Starting Analysis
4.5.1 Starting and Ending Analysis
Click to start analysis. The system controller operates in the following way.
(1) If a sequence table has been set, the table is registered to the analysis queue and
analysis is performed in accordance with the table settings. If there is already a
sequence registered to the analysis queue, however, analysis starts from the first
sequence in the queue.
(2) If a sequence table has not been set, analysis is performed in accordance with the time
program.
(3) If neither a sequence table nor a time program has been set, the analysis starts and
does not stop.
With this system controller, it is possible to output a start signal to connectors OUT1 to
OUT4 on the back of the system controller or to the optical-link interface (for
Chromatopac) each time analysis is started. It is also possible to automatically auto-
zero the detector.
Forcibly Stopping Analysis
Click to forcibly stop analysis.
Analysis is stopped forcibly.
Analysis cannot be restarted from a sequence that was stopped forcibly.
If analysis is forcibly stopped during autosampler operation, [Stop] is displayed in the
status display (when using an autosampler other than SIL-30A/20A series). In this
case, click to initiate automatic rinsing of the flow line.
Pausing Analysis Operation
Click to pause analysis operation.
[Pause] is displayed in the status display when the current analysis operation is completed.
Analysis operation enters waiting status when the current (single) analysis operation is
completed (or the current (single) time program in the analysis file is completed).
Click again to resume analysis from the next operation.
Canceling "Cooling Down" or "Power Down"
If a shutdown is set in the analysis queue, [Cooling Down] or [Power Down] is displayed in the
status display after the sequence has been completed. If is clicked, the shutdown is
canceled and [Ready] is displayed.
