The upper tubing chase routes tubing from the eluent organizer to the component panel. The lower tubing chase routes tubing from the component panel, through the interior of the system, and then to the rear panel.
Two additional tubing chases (on the left and right sides of the component panel) direct tubing from the autosampler to the injection valve, depending on where the autosampler is placed to the left or right of the Dionex Inuvion IC System. For more details, see Injection valve.
