Installing the amperometric detector
The 940 Professional IC Vario provides enough space for two detectors
and additional accessories in the detector chamber. The detectors are
available as separate devices and are supplied with separate manuals.
Placing the detector in the instrument
Follow the instructions in the chapter
Inserting the detector
in the manual
for the detector.

Connecting the sample degasser (optional)
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.
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 two minutes when the sample
degasser is connected.
Accessories
For this step, you need the following accessories:
￭
2 × pressure screw, long (6.2744.090)
