Full loop injection
The sample loop is filled completely (quantitatively) with sample. This type
of injection results in excellent reproducibility.

Full loop injection
The injection valve is in INJECT position. The sample needle pene-
trates the vial with the air needle. An overpressure channeled in
through the air needle ensures that no air or steam bubbles form
during the aspiration of the sample.
