The column compartment can hold one or two column switching valves. To ensure optimum operation of the column switching valve, observe the following guidelines:
Operating, storing, or shipping the valve below 0 °C with water in the fluid passages may cause failure of the sealing surfaces.
Install Viper fitting connections to connect the capillaries to the valve.
Clean the valve by flushing all lines with an appropriate solvent. The nature of the solvent to be used depends on the samples and the mobile phases that are used.
