252 ChromGate® Preparative Option
Enter the flow rate of the injection pump during the injection. If no
injection is prepared, the pump is stopped; during a run the pump and
valve cannot be controlled beside the programmed stacked injection.
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.
Pump Settings
Control Pressure Limits (MPa)
Enter the values for the desired pressure limit. 0 will disable the software
control of the pressure. Keep in mind that the pressure for the sample
loading may be different from the system pressure during a run if a
different flow rate is used or if you use a sample loop. Note that for a
pump S 100 without pressure transducer this option is not accessible.
Solvent
Enter the name of the solvent.
Stacked Injections [>>…]
The option Stacked injections allow to define additional injections during a
run. Such injections can be programmed either for the autosampler 3950 or
the injection module (please refer the Instrument Setup for the autosampler
3950 for details of the stacked Injection setup of the autosampler. Click on
the [>>…] – button to open the Stacked Injections table dialog.
