Using valves in FPLC is most often necessary due to manual injection, column switching or fractionation. But also common analytical HPLC applications can be improved by adding valves. Widespread analytical application areas are for example column screenings to find the suitable column. A large variety of valves is available, but not all are suitable for the screening of pressure sensitive columns. This note describes an application of a KNAUER 8 port 2-position valve in a screening process with Eurokat columns.
