Replacing the CO
2
adsorption cartridge CW
Capacity loss
The adsorption capacity of the CO
2
adsorption cartridge CW is limited and
decreases over time. This is indicated by an increasing baseline (since more
CO
2
gets to the detector). The CO
2
adsorption cartridge CW has to be
replaced once the adsorption capacity is depleted. CO
2
adsorption car-
tridges CW are available under the order number 6.2837.100.
Maintenance interval
The CO
2
adsorption cartridge CW (6.2837.100) loses capacity over time.
Depleted cartridges change their color to violet. New cartridges are white.
The CO
2
adsorption cartridge CW needs to be replaced:
￭
once
¾
of its color has changed to violet.
￭
after 12 months at the latest.
Removing the depleted CO
2
adsorption cartridge CW
1
Remove the depleted CO
2
adsorption cartridge CW from the adsorp-
tion cartridge holder.
2
Remove the
Air in
capillary of the Metrohm CO
2
Suppressor (MCS).
3
Professionally dispose of the depleted CO
2
adsorption cartridge CW.
