Connecting the 2D-LC Valve, ASM (G4243A)
In contrast to the standard 2D-LC Valve (G4236A) Agilent recommends using a
counter-current configuration for the ASM 2D-LC Valve (G4243A) when working
in ASM mode. This section describes the setup for a counter-current
configuration of the ASM Valve. For the concurrent setup, please refer to
concurrent configuration of the ASM 2D-LC Valve in the 2D-LC Software. You find
the Valve topology configuration screen in OpenLab CDS ChemStation Edition
under Instrument > 2D-LC Configuration.
The installation of a 2D-LC system depends on which modules you are using for
which 2D-LC mode and is described above. The connection scheme is displayed
in the graphical user interface of the 2D-LC Configuration as Valve Topology:
