About the Injection Valve

The injection valve has six ports and can be moved manually between two
positions. In the LOAD position, the mobile phase is led from the pump
directly to the column, allowing you to inject your sample into the sample loop.
In the INJECT position, the mobile phase is led through the sample loop,
flushing the contents of the loop onto the column.
