3.3.1
Eluent Flow Path Connections in the AutoSuppression Recycle Mode
Depending on the specific components (analytical column, conductivity cell, back pressure
coils) in the system, ¼-28 or 10-32 ferrule/bolt liquid lines may be required. All necessary
tubing and fittings are supplied in the detector or Dionex RFC-10 or Dionex RFC-30 Ship Kits.
To purchase or assemble ¼-28 or 10-32 ferrule/bolt liquid lines, refer to, “Dionex Liquid Line
Fittings.” Always use 0.005” i.d. PEEK tubing with 10-32 ferrule/bolt fittings on 2 mm
systems. Use 0.010” i.d. PEEK tubing with 10-32 ferrule/bolt fittings on 4 mm systems when
possible. Avoid adding dead volume to the system by keeping all eluent lines as short as
possible.
A.
Install the Dionex ERS 500, Dionex ERS 500e or Dionex AERS 500 Carbonate inside
the Dionex ICS Module.
B.
Connect the outlet of the analytical column to the ELUENT IN of the suppressor
(see
).
C.
Connect the ELUENT OUT port of the suppressor to the inlet of the conductivity cell
(see
).
3.3.2
Regenerant Flow Path Connections in the AutoSuppression Recycle Mode
Connect the back pressure coil(s) between the CELL OUTLET port and the REGEN IN port
(see
and
). The back pressure coils are provided in the Gas Separator Waste
Tube Components Assembly (Item # 045825) for 4 mm systems. The backpressure coils for 2
mm systems are provided in the microbore tubing kit (Item # 052324) (see
Figure 5
and
Section
2
). The back pressure coils are provided in the Gas Separator Waste Tube Components
Assembly (Item # 045825) for 4 mm systems. The backpressure coils for 2 mm systems are
provided in the microbore tubing kit (Item # 052324).
The Dionex
ERS 500, Dionex ERS 500e or Dionex AERS 500 Carbonate must be operated
with the Gas Separator Waste Tube (Item # 045460).

Installation in Thermal Chamber
A.
Installation instructions for Dionex ICS-3000/5000/5000+ DC.
1.
Install the suppressor using the suppressor holder on the CD in the upper
compartment. Ensure the upper compartment temperature is set to a value no
greater than 40°C and temperature control is turned on. It is recommended that the
upper compartment is kept cooler than the lower compartment. If using a single
zone DC, do not set the temperature above 40°C. For best noise performance the
upper compartment can be set to 20° C.
B.
Installation instructions for Dionex Integrion:
2.
Install the suppressor using the suppressor holder on the Conductivity Detector in
the detector compartment (bottom right door). If the Dionex Integrion is fitted with
detector compartment temperature control, ensure the detector compartment
temperature is set to a value less than 40°C and temperature control is turned on. It
is recommended that the detector compartment is kept cooler than the column
