Connecting the sample degasser (optional)
Gas bubbles in the sample lead to poor reproducibility, as the quantity of
sample in the sample loop is not always the same. Therefore, we recom-
mend degassing samples that contain gas before injection.
NOTE
The sample degasser does not have to be connected. We recommend
only using the sample degasser if the application requires it.
The rinsing time increases by at least 2 minutes when the sample
degasser is connected.
