4.3.10.1 Instrument Configuration
Solvent Controls
• Add Solvent — Click this button to enter a solvent
name. PeakTrak can store up to 16 solvent names. For
assistance in selecting appropriate solvents, see the
SOLVENT SELECTION TABLE [ON-LINE].
• Remove Solvent — Click this button to open a list of
all entered solvent names. Select the names you want to
remove and then click the OK button.
• Enable Solvent Level Sensing — If this option is
selected, the module will check the solvent levels before
and during a run. PeakTrak 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 1–4, 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 4 cm above the
weighted filter.
• Waste Level Sensing — The module can detect full
container conditions if the air line is placed in the waste
collection container. If waste level detection is desired
enable the waste level sensing feature (recommended).
Otherwise, uncheck this option to disable this feature.
