Dionex ICS-5000 Operator's Manual
Cartridges for the following components are available: carbonate removal
device (CRD); suppressor, guard and separator columns; and EG degasser.
NOTE
If the IC Cube does not include a CRD or suppressor, bypass
cartridges must be installed. Bypass cartridges provide the
internal plumbing connections required for eluent and regen-
erant flow between IC Cube components.

The CRD 200 (Capillary) cartridge (P/N 072054) contains a CRD 200
Carbonate Removal Device (Capillary). The CRD 200 (Capillary) removes
the carbonate peak contributed by the sample in hydroxide eluent chemistries.
Removal occurs immediately after suppression of the eluent, before the
sample reaches the detector. The CRD 200 (Capillary) is optimized for
operation at the flow rate range typically used with capillary columns.
The CRD and tubing connections inside the cartridge are not accessible.
Tubing exits the front of the cartridge to allow connection to other capillary
IC components.
Installation of a CRD 200 (Capillary) is optional. However, if one is not used,
a CRD bypass cartridge (P/N 072056) must be installed. The bypass cartridge
