12.5.3 Setting column parameters
For capillary columns, the column inner diameter, length, and film thickness are used to cal-
culate the column flow rate and linear velocity. Enter the column inlet pressure, and the col-
umn flow rate and linear velocity are calculated based on the column parameters.
Alternatively, by entering the column flow rate and linear velocity valves, the column param-
eters are used to calculate the corresponding column inlet pressure.
