12.2.3 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.
12.2.3.1 Screen description
Select [Column] (PF menu) from the [FLOW] key main screen to display the Column
Diam. screen shown in Fig. 12.5.5.
12.2.3.2 Parameter list
COLUMN I.D.
Range: 0.01−6.00 mm, Default: 0.32 mm
COLUMN LENGTH
Range: 0.1−250.0 m, Default: 25.0 m
FILM THICKNESS
Range: 0.00−300.00 µm, Default: 0.50 µm
Set the internal diameter, the length and film thickness of the capillary column in use.
These parameter values are used for calculation (or the backward calculation) of the
column head pressure based on the column flow rate or the linear velocity.
