µL Pick-up Injections 

 

The switching sequence for a µl pick-up injection is 
schematically shown in the following figures : 

1.  Initially the injection valve is in the Inject position. The 

sample needle has entered the vial of mobile phase. This to 
avoid disturbance of the chromatogram with an additional 
peak that could come from solvent that is different from the 
mobile phase. 

 

 

µL Pick-up injection: initial position.
