Linear flow rates


Introduction

Linear flow rates (cm/h) can be specified for Flow instructions. The volume flow rate is calculated from a specified linear flow rate and the column diameter as given in the column definition.


How to use linear flow rates

The table describes how to use linear flow rates.

Step

Action

1

Select a specific column on the Variables tab of the Run Setup,

or

Insert a column for the Base instruction of the block in the Text Instructions Editor.

2

In the Instruction box of the Text Instructions editor, select Flow and select the Linear Flow option as shown in the illustration below:

Note: If the column is changed, you will be asked if the linear flow rate or the default flow rate should be used. If the linear flow rate cannot be used due to the max flow rate of the system or new column, you will be advised that the max flow rate will be used instead.
