Run Estimation
You can at any time view the estimated solvent consumption
and the required waste capacity:
»
When setting up the run by pressing Run
Estimation below the gradient table.
»
During the run by pressing Run Estimation in
the Solvent Setup view; see Figure 28.
If there is not enough solvent or waste capacity for the run when
the run is started, the system will notify the user.
Note: The available volume displayed in the Run Estimation
dialog is equal to the current level (in the Solvent Setup view)
minus the reservoir's stop volume; see Figure 28.
Figure 28. To view the estimated solvent consumption and the required
waste capacity for the rest of the run, press Run Estimation in the Solvent
Setup view. The estimations are updated in real time.
Solvent and Waste Estimations and Notifications
Solvent and Waste Notifications
When using the liquid level sensors for solvent and waste
monitoring:
Notification
Description
The solvent surface is 60 mm from the bottom of
the reservoir. In this example the notification is for
solvent inlets S1 and S2.
When the solvent surface is 30 mm from the bottom
of the reservoir, the run is automatically paused and
the user will be prompted to refill the solvent(s).
The solvent monitoring has been turned off for
the rest of the run by the user. The monitoring is
automatically turned on again when the run has
been completed.
The waste level is above 85% of the set waste
reservoir capacity.
When the waste level is at 95% of the set capacity,
the run is automatically paused and the user will be
prompted to empty the waste reservoir.
When the distance between the sensor and the
waste liquid becomes smaller than allowed, the
run is automatically paused and the user will be
prompted to empty the waste reservoir. See "Safety
Stop Limit for Waste" below.
Safety Stop Limit for Waste
To ensure that the waste reservoir cannot be overfilled, the
pump operation in progress is immediately paused if the
distance between the sensor and the waste liquid becomes
smaller than allowed. This is useful if e.g. the operator by
mistake is using a waste reservoir that is smaller than the one
that has been assigned to the solvent inlet in the software.
