5.5.3 Setting the Flow Rate, Flow Acceleration, and Flow Deceleration
In Chromeleon or on the pump menus, you can set how fast the pump starts delivering with
the selected flow rate (flow acceleration) and how fast the pump flow is reduced (flow
deceleration).

If the values are too low, it will take accordingly long for the pump to reach the necessary
flow, and thus to build up the necessary pressure or reduce the flow and thus, the pressure
as required.

If the values are too high, this may or reduce the lifetime of the column.
Dionex recommends that you set these parameters to values between 1/3 and factor 3 of the
(column) flow rate.
To set the flow rate, flow acceleration, and flow deceleration in Chromeleon
1. In Chromeleon, open the Commands dialog box for the pump (

page 65).
2. Select Flow and enter the desired flow rate in the Nominal box.
The property is listed under PumpModule > [Pump Device Name] (

page 37).
The allowed flow rate range is indicated in the Properties dialog for the pump
(

page 39). In the Properties dialog box, you can change the upper and lower limit for
the flow rate within the allowed range.
3. Under MaximumFlowRampUp , check and change the flow acceleration setting if
necessary.
Under
MaximumFlowRampDown , check and change the flow deceleration setting if
necessary.
To set the flow rate, flow acceleration, and flow deceleration on the pump display
1. Select the Control menu.
2. Select Flow rate and enter the desired value.
Tip: You can enter the flow rate also by selecting Set flow on the navigation
bar.
3. On the pump display, select the Preferences menu.
4. Under Flow acceleration , check and change the flow acceleration setting if necessary.
Under Flow deceleration , check and change the flow deceleration setting if necessary.
