Connecting the MCS
1 Connecting the MSM
Connect the eluent output capillary (labeled with Detector) using a
6.2744.090 long PEEK pressure screw (35-4) to the MCS inlet (35-1).
2 Connecting the detector
Connect the detector input capillary (37-3) using a long PEEK pres-
sure screw 6.2744.090 (35-4) to the MCS output (35-2).
CAUTION
If the MCS is not used, the input and output should be sealed with
6.2744.220 stoppers.

Installing the adsorption cartridges
For effective CO
2
removal, the air sucked through the degassing cell
should be as low in CO
2
as possible. To achieve this, the air is aspirated
through a 6.2837.000 CO
2
adsorption cartridge (36-4).
Moisture can block the CO
2
adsorption cartridge. In order to prevent this,
