Flush the Columns
NOTE Flushing is required only for new guard
and separator columns.
To flush the guard column:
1. Remove the guard and separator columns
from their boxes.
2. Remove the fitting plugs from the ends of
each column.
3. Orient the guard column with the arrow on the
label pointing in the direction of flow (away
from the injection valve) and connect
GUARD
IN
to the inlet of the guard column.
4. Remove the union from
GUARD OUT
and
connect
GUARD OUT
to the guard column
outlet.
5. Disconnect
COL IN
from the union connecting
it to
COL OUT
(see Figure 31 , item ).
6. Direct
COL IN
(the guard column outlet) to a
waste container.
7. On the Dionex ICS-900 Control panel, set the
flow rate to the recommended rate for the
column.
8. Start the pump and let it run for 15 minutes.
To flush the separator column:
1. Orient the separator column with the arrow on
the column label pointing toward the
conductivity detector cell and connect
COL IN
to the separator column inlet.
2. Remove the union from
COL OUT
and connect
COL OUT
to the separator column outlet.
3. Disconnect
ELUENT IN
from the union
connecting it to
ELUENT OUT
(see Figure 31 ,
item ).
4. Direct
ELUENT IN
to a waste container.
5. Start the pump and let it run for 15 minutes.
6. Reconnect
ELUENT IN
to the union on
ELUENT
OUT .
The column is now connected directly to
the cell inlet. This is a temporary connection.
Install the Columns
1. Push the guard column onto the clips (see
Figure 32 ).
2. Push the separator column onto the clips (see
Figure 32 ).
Connect Backpressure Coils
Connect backpressure coils between the
conductivity cell outlet and the regenerant bottle
inlet (see
Figure 32 ).
1. Determine the number and type of
backpressure coils required for your system.
Standard bore systems: Use one or two
black backpressure coils (P/N 045877),
supplied in the Dionex ICS-900 Ship Kit.
