Multiple Column Selection

With the 6-column selection valve (G4234A/C) and the capillary kit for column selection you can set up your system for use with up to 6 columns as displayed in Multiple Column Selection (Example of Schematic Setup for 6-Column Selector). Or you can use the system with 5 columns and one flow path for flushing the system. This setup allows you to switch between columns for faster method development. The multicolumn setup might also be used, if several operators are sharing the system.
