Mounting filter screw
￭ Screw the filter screw (47-3) back into the tubing olive (47-1) and
tighten by hand. Then additionally tighten with two 6.2621.000
adjustable wrenches.

4.13.1 Replacing the CO
2
adsorption cartridge
The CO
2
adsorption cartridge 6.2837.000 (32-4) must be replaced regu-
larly. This is because of blockages and losses in capacity.
Blockage
Moisture can block the CO
2
adsorption cartridge. This is revealed by a
change in color of the cartridge material (the orange part becomes color-
less). As the air flow is reduced, the vacuum becomes lower. To protect
the CO
2
adsorption cartridge, an H
2
O adsorption cartridge (32-7) is instal-
led upstream. Regular regeneration (see Chapter 4.13.2, page 96) of
the H
2
O adsorption cartridge extends the service life of the CO
2
adsorp-
tion cartridge.
Capacity loss
The adsorption capacity of the CO
2
adsorption cartridge is limited.
Depending on the period of operation and laboratory environment, the
adsorption capacity will diminish over time. This is manifested in a rising
baseline (as more CO
2
reaches the detector).
4.13.2 Regenerating the H
2
O adsorption cartridge
The function of the H
2
O adsorption cartridge is to protect the CO
2
adsorp-
tion cartridge against moisture. The service life of the H
2
O adsorption car-
tridge depends on the moisture content of the ambient air. Moisture
reduces the capacity of the H
2
O adsorption cartridge (which can be
observed by a change in color). Before the color changes in the entire fill-
ing material (from orange to colorless, with Fluka Order No. 94098), the
H
2
O adsorption cartridge should be regenerated (see information sheet).
The filling material is replaced during regeneration:
1
Allow material to dry loose (not in cartridge) at 140 °C overnight and
refill. Or dispose of the old material, and fill with new material.
2
Cover the packed material with wadding.
