889 IC Sample Center

4.4 

Partial loopfill injection

The switchover sequence for the partial loopfill injection is as follows:

1 Initial situation

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.

 

2 Rinsing the aspirating line
