n Setting the low-pressure gradient mode《LPGE CYCLE》
Set the operation mode of low-pressure
gradient.
Set Value Low-Pressure Gradient Mode
0
(Standard)
The mode is automatically selected according to the flow rate.
2.0000 mL/min or less: 4-cycle mode
2.0001 mL/min or more: 8-cycle mode
2
2-cycle mode
Select this mode when using a low-capacity mixer with 300 µL or less
internal capacity.
In any other mode, concentration will be more uneven resulting in a
wavier baseline on the detector.
4
4-cycle mode
This mode is suitable for a mixer with approximately 0.5 mL internal
capacity.
8
8-cycle mode
This mode is suitable for a mixer with a 1.5 mL or higher internal
capacity.
n Setting the purging time《PURGE TIME》
Set the purging time.
The value can be set in the range from 1
minute to 20 minutes in one minute
increments.
n Setting the purging flow rate《PURGE FLOW》
Set the purging flow rate. This setting is
effective for both purging with the
[PURGE] operation in the instrument and
auto purging with the system controller.
The value can be set in the range from 0.1 mL/min to 10.0 mL/min in 0.1 mL/min
increments.
The flow rate set here is approximate for replacing the mobile phase in the
pump.
