Installing adsorption cartridges
The aspirated air has to have the lowest CO
2
content possible in order for
the CO
2
to be removed from the eluent efficiently. In order to achieve this,
the air is aspirated through a CO
2
adsorption cartridge CW (6.2837.100).

For this step, you need the following accessories:
￭
Adsorption cartridge holder (6.2057.080) with two clips.
￭
CO
2
adsorption cartridge CW (6.2837.100)
All of the parts are located in one accessory kit: Vario/Flex SeS
(6.5000.020).
