Connecting the sample degasser (optional)

Accessories
930 Compact IC Flex Oven/Deg/MB (2.930.2180)
Connecting the detector to the eluent path
NOTICE
The separation column is not inserted into the instrument until it is
being started up for the first time. Until then, the detector inlet capillary
has to be connected directly to the column inlet capillary using a cou-
pling (6.2744.040).
For this step, you need the following accessories:
Coupling (6.2744.040)
￭
2 × pressure screw (6.2744.010)
￭
Gas bubbles in the sample lead to poor reproducibility, as the amount of
sample in the sample loop is not always the same. Therefore, we recom-
mend degassing samples that contain gas before injection.
NOTICE
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 two minutes when the sample
degasser is connected.
For this step, you need the following accessories:
2 × pressure screw, long (6.2744.090)
￭
PTFE capillary (6.1803.040)
