FIGURE 1-1. Schematic Diagram of the Switchos II Advanced Microcolumn Switching Unit
The Switchos II Advanced Microcolumn Switching Unit includes the following
components:
• 10-Port Switching Valves - low dispersion valves assure dead volume free
connection of any Micro- or Nano LC column (e.g., Fusica, NanoSeries, Micro-
and Nano-Precolumns, etc.). Two fast motor-driven actuators control the valve
positions (6 port valves are incorporated into some systems).
• 4-Way Solvent Selection Valve - allows for the automatic selection of up to 4
different solvents without the need of pump shut down or tedious purging.
One fast motor-driven actuator switches the valve into the selected position.
