This 12 port plumbing arrangement is simply a dual 6 port diagram; while sample 1 is loaded and subsequently injected onto Column 1, Sample 2 is loaded and injected onto Column 2. If sample inlets cannot be connected in the inject (B) position, simply reverse ports 2 and 7. As with 10 port valves, the 12 port is capable of a wide variety of sample injection and switching applications.
