End of stage trigger point
Final stage
Once the evaporation process is under way,
the ∆T value peaks when solvent
evaporation is most rapid. The system sets
an end of stage trigger point at a percentage
value of the ∆T peak (the percentage value
is defined within the method). The screen
shows the end of stage trigger point as a
horizontal dotted line and displays
Running
to AutoStop
.
When the ∆T value drops to the end of
stage trigger point, the evaporator proceeds
to the next stage. This may be a new stage
(in a multi stage method) or it may be the
final drying stage.

Once in the final drying stage, the screen
shows a vertical dashed line at the projected
end of run time (defined within the method)
and displays

.
The system continues to operate for the
defined period and then stops automatically.
