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.
Accessories
For this step you need the following accessories:
￭
2 × pressure screw, long (6.2744.090)
￭
PTFE capillary (6.1803.040)
Connecting the sample degasser
CAUTION
If the sample degasser is not used, the input and output must be
sealed with threaded stoppers (6.2744.220).
