3.5 Injection valve
Function of the Injection valve
The Injection valve is used to direct sample onto the column. The valve enables usage
of a number of different sample application techniques.
The Injection valve is labeled V9-Inj for ÄKTA avant 25 and V9H-Inj for ÄKTA avant 150.
A sample loop or a Superloop™ can be connected to the Injection valve and filled either
automatically using the Sample pump or manually using a syringe. The sample can also
be injected directly onto the column using the Sample pump.
For instructions on how to connect and use sample loops, see Section 5.7 Sample appli-
cation, on page 189.
