• Enable Solvent Level Sensing — (Rf+ systems,
including those equipped with 4x) If this option is
selected, the system will check the solvent levels before
and during a run. The system will alert you if a solvent
level becomes too low. Note that the solvent level
monitoring option does not control the operation of
Waste Solvent Level monitoring. Waste level sensing is
always enabled at the beginning of a run.
• Minimum Solvent Level — This value is
density-dependent, thus a range is given. To understand
the range, consider that dichloromethane is more dense
than hexane. If the selected range is 1–2, an alert would
be triggered when the dichloromethane falls to about 1
cm above the bottom of the weighted filter. At the same
selected range, an alert would be triggered when the
hexane solvent level falls to about 2 cm above the
weighted filter.
CombiFlash Rf Name Enter a name for the system. This name
will appear in the title bar of the Main window. The name will
also appear in run summaries. Unique names are helpful
when operating more than one system.
Time Zone Select your local time zone.
Set Date/Time Click this button to set the date and time. From
