❑ In the load position, a syringe is used
   to wash and load the loop with fresh
   sample at atmospheric pressure.

❑ High-pressure flow from the pump to
   the column passes through the lower
   left segment of the valve.

❑ When the valve is rotated 60
   counterclockwise, the content of the
   sample loop is injected into the
   column at high pressure.
