3 Connection to the detector
Connect the detector input capillary with a long pressure screw
(6.2744.090) to the MCS output (labeled Out).
CAUTION
If the MCS is not used, the input and output must be sealed with the
threaded stoppers (6.2744.220).
3.13.3 Installing adsorption cartridges
The suctioned air has to have the lowest CO
2
content possible in order for
the CO
2
to be removed from the eluent as efficiently as possible. In order
to achieve this, the air is aspirated through a CO
2
adsorption cartridge
(6.2837.000).
However, the CO
2
adsorption cartridge is sensitive to humidity; the CO
2
adsorption cartridge becomes clogged when wet. In order to protect the
CO
2
adsorption cartridge, an H
2
O adsorption cartridge (6.2837.010) is
also installed.
Accessories For this step you need the following accessories:
￭ Adsorption cartridge holder (6.2057.080) with 4 clips, an adapter
(6.1808.190) and a piece of PVC tubing.
￭ CO
2
adsorption cartridge (6.2837.000)
￭ H
2
O adsorption cartridge (6.2837.010)
All of the parts are located in one accessory kit: Vario/Flex SeS
(6.5000.020).
Installing the adsorption cartridge
CAUTION
The following preparatory steps absolutely must be carried out for CO
2
suppression to operate correctly.
Preparing the adsorption cartridges:
￭ Prepare the H
2
O adsorption cartridge for use as specified in the provi-
ded leaflet.
￭ Remove the protective cap on the tip of the CO
2
adsorption cartridge.
