Module
Column valve V9-C or V9H-C
pH valve V9-pH or V9H-pH
Outlet valve V9-O or V9H-O
UV monitor U9-M
Conductivity monitor C9
Built-in fraction collector
Core modules
Core modules need to be installed for the system to run. They are mandatory in the
software.
All standard modules except the built-in fraction collector are considered core modules.
Description of optional modules
The following modules may be added to the flow path.
Module
Second Inlet valve A
V9-A2 or V9H-A2
ÄKTA avant Operating Instructions 29101556 AB
Description
Column valve which connects up to five columns
to the instrument, and directs the flow to one
column at a time. The column valve features two
integrated pressure sensors.
Allows the user to choose flow direction through
the column, or to bypass the column.
Valve which enables the pH electrode to be includ-
ed in the flow path or by-passed during a run. The
pH electrode may be calibrated when installed in
the pH Valve. It also enables the flow restrictor to
be included in the flow path (default position) or
by-passed during a run.
Valve which directs the flow to the fraction collec-
tor, any of the ten outlet ports or waste.
Monitor which measures the UV/Vis absorbance
at up to three wavelengths simultaneously in the
range 190 to 700 nm.
Monitor which continuously measures the conduc-
tivity of buffers and sample solutions.
Built-in fraction collector. A cooling function pro-
tects the fractions from heat degradation.
Description
Second inlet valves for System pump A, to extend the
number of inlets up to 14.
