Full loop injection

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

1 Initial situation

Figure 13

Full loop injection

The injection valve is in 

INJECT 

position. The sample needle penetrates

the vial with the air needle. An overpressure channeled in through the
air needle ensures that no air or steam bubbles form during the aspi-
ration of the sample.
