The reagent lines are labeled to indicate the solution going through that line. The carrier
line is always connected to port 2 of the valve. The sample line is always connected to
port 6 of the valve.
Note: The manifold diagram examples have only one tee connector.
Every intersection of two reagent lines represents a tee connector
Tee connectors combine two reagents. The tee has three ports; two side ports (inlets)
where the two reagent lines are connected and a top port (outlet) which may be
connected to a mixing coil or whatever is indicated in the manifold diagram.
