2.5 Connection of capillaries
The 853 CO
2
Suppressor is connected between the suppressor module
«MSM II» and the detector block.
1 Suppressor module «MSM II» – 853 CO
2
Suppressor
• Connect the "Suppressor outlet capillary for eluent" (marked
with "Detector") to the "Eluent in" inlet (2) of the 853 CO
2
Suppressor using a 6.2744.010 Pressure screw.

Suppressor – Detector block
• Connect the "Inlet capillary to detector block" to the "Eluent
out" outlet (1) of the 853 CO
2
Suppressor using a 6.2744.010
Pressure screw.
2.6 Cartridges
Effective CO
2
removal requires that the air pumped through the de-
gassing cell should contain as little CO
2
as possible. This is achieved
by drawing the air through a 6.2837.000 CO
2
Absorber Cartridge.
The CO
2
Absorber Cartridge can become blocked by moisture. This
can be prevented by connecting a 6.2837.010 H
2
O Absorber Car-
tridge in front of it.
The cartridges are installed as follows:
1 Remove caps
• Remove the sealing caps at the inlet and outlet of each
cartridge.
2 Connect CO
2
Absorber Cartridge
• Insert the CO
2
Absorber Cartridge (3-layer filling, blue-brown-
gray) in the coupling 9.
3 Connect H

Cartridge
• Insert the 6.1808.190 Adapter in the CO
2
Absorber Cartridge.
• Attach the 6.1801.140 PVC tubing to the 6.1808.190 Adapter.
• Insert the H
2
O Absorber Cartridge (filled with orange drying
beads) into the 6.1801.140 PVC tubing.
4 Attach the cartridges
• Attach the two cartridges to the left-hand mounting support of
the 861 Advanced Compact IC or 820 IC Separation Center
using two 6.2027.070 Holders.
