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.
