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 pure 25 and V9H-Inj for ÄKTA pure 150.
A sample loop or a Superloop can be connected to the injection valve and filled either automatically,
using a Sample Pump or System pump A, or manually, using a syringe. The sample can also be injected

For instructions on how to connect and use loops, see Section 5.7 Sample application, on page 180.
