9.8.7 Manual instructions - Advanced
The following table describes the advanced manual instructions available for ÄKTA avant.
DescriptionInstruction name
By using Pressure control the method can be run with
the set flow rate without the risk of method stop due to
pressure alarm. Pressure control is enabled in the instruc-
tion System flow or Sample flow. Pressure control pa-
rameters provides the P and I factors used in the regu-
lator and can be adjusted for different columns.
Pressure control parame-
ters
Pressure control min flow rate can be set either as volu-
metric or as linear flow. A column type must be selected
before using linear flow.
Enables column packing at constant pressure. The sys-
tem pump automatically adjusts the flow rate within
the specified Minimum allowed flow rate Maximum
allowed flow rate range. The goal is to reach and keep
the set Pressure at the selected Pressure sensor using
the P and I factors set in the Constant pressure flow
parameters instruction. The total volume is continuously
updated using the actual flow rate.
Constant pressure flow
Both pressure control flow rates can be set either as
volumetric or as linear flow. A column type must be se-
lected before using linear flow.
Note:
When Constant pressure flow is used, the P and I
factors set in the Constant pressure flow parame-
ters instruction are used to control the pressure, in-
stead of the P and I values set in the Pressure control
parameters instruction.
Pressure sensor Delta column pressure is available
only when column valve V9-C or V9H-C (5-columns)
is selected in the component list.
Sets the values for the P and I factors needed to keep
a constant pressure by varying the flow rate. The signal
used for pressure control is set in the instruction Con-
stant pressure flow.
