Fluidic Scheme Mapping
The NGC instrument supports up to four inlet valves (two buffer and two sample
inlet valves), three column-switching valves, and two outlet valves. When more than
one of a specific valve type is installed, ChromLab automatically detects the valves
and maps the fluidic scheme to their default positions on the NGC instrument. For
example, when two or more inlet valves are present in the fluidic scheme,
ChromLab automatically detects the position of the valves on the NGC instrument
(starting from the left side of the bottom tier) and assigns the first valve Inlet A.
If the configuration of your NGC instrument is different than the default, or if you
changed your fluidic scheme, you must manually map the valves on the instrument
to their locations on the fluidic scheme. This is done using the Fluidic Scheme
Mapping dialog box.
Note: If you have only two inlet valves on your NGC instrument and both
valves are designated as buffer inlets, you do not need to map them. The
system automatically determines their locations and function on the instrument.
The Fluidic Scheme Mapping dialog box displays the current fluidic scheme in the
upper pane and the current NGC instrument configuration in the lower pane.
ChromLab automatically detects which valves in the fluidic scheme can be mapped.
These valves appear color-coded in the upper pane. The corresponding valves
appear in the same color code on the instrument map in the lower pane, in relative
location to the mappable modules on the NGC instrument. All other modules
appear inactive in the lower pane.
