ChromGate® Preparative Option 253
Number of Injections
Enter the number of stacked injections. If you, e.g., enter “5”, two stacked
injections will be made; in addition of the initial injection 6 injections at all
will be made per run. Please make sure that you have enough samples
for the entered number of injection.
Injection Volume
Enter the desired injection volume in ml.
Injection Flow
Enter the flow rate of the injection pump during the injection. If no
injection is prepared, the pump is stopped. During a run the injection
module’s pump can only be controlled using the option “Direct control
during a run” (please refer the manual’s appropriate chapter Runtime
Settings, page 141).
Injection Duration
The duration of the injection is calculated from the injection volume and
the injection flow. The reduced flow during start and stop of the pump is
taken into account with 6 seconds in sum.
Time between Injections (min)
Enter the time between the injections. The value must be higher than the
time calculated for the injection duration.
Click the Apply-button to apply the settings into the Stacked injections
table.
