6. Install an end-line filter on the eluent line (see Section 3.4.3).
7. (Optional) Pressurize the reservoir.
The Dionex ICS-1100 does not require pressurized reservoirs.
However, if eluent is manually degassed or is sensitive to
contamination, Dionex recommends pressurizing the reservoir with
helium or nitrogen.
The air regulator accessory bracket and other items needed for
pressurizing the eluent reservoir must be ordered separately
(P/N 060054). For more information, refer to the Dionex ICS-1100
installation instructions.
3.4.3 Filter the Eluent
Filtering removes small particulates in the eluent that may contaminate
the pump check valves and cause erratic flow rates or loss of prime. An
end-line filter (P/N 045987) is provided in the Dionex ICS-1100 Ship Kit
(P/N 057905) for this purpose.
Install the end-line filter on the end of the eluent line, inside the reservoir.
Verify that the end of the filter extends to the bottom of the reservoir and
that the filter is submerged in eluent. This prevents air from being drawn
through the lines.
3.4.4 Fill the Reservoir
Fill the reservoir with the prepared eluent.
3.4.5 Set the Eluent Level
After filling the reservoir, enter the volume of liquid in the reservoir on
the Dionex ICS-1100
Control panel on the Chromeleon panel tabset (see
Figure 3-5
).
The Dionex ICS-1100 determines the eluent usage by monitoring the flow
rate and the length of time the pump is on, and updates the
Eluent Bottle
volume as the eluent is depleted. A warning appears if the level falls
below 200 mL. Warnings are repeated at 100 mL and 0 mL.
