Fig. 5: Example for column switching with a 2-position, 10-port column switching valve
In position 10-1, column 1 analyzes while column 2 re-equilibrates. In position 1-2,
column 2 analyzes while column 1 re-equilibrates.
• Two multi-position valves are the appropriate choice for applications with several
columns, for example, for method scouting.
