ICS-2100 Ion Chromatography System

3.4 Set Up the Eluent Reservoir
The ICS-2100 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 ICS-2100 installation instructions.
3.4.1 Filter the Deionized Water
Filtering removes small particulates in the deionized water 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 ICS-2100 Ship
Kit (P/N 064375) for this purpose.
Install the end-line filter on the end of the deionized water 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 deionized water. This prevents
air from being drawn through the lines.
3.4.2 Fill the Reservoir
Fill the reservoir with ASTM filtered, Type I (18-megohm) deionized
water.
3.4.3 Set the Eluent Level
After filling the reservoir, enter the volume of liquid in the reservoir in
one of the following locations:
• On the HOME page in the Eluent Level field (see Figure 3-5)
• In the Eluent Bottle field in the Pump Settings window (accessed
from the ICS-2100
Control panel on the Chromeleon panel tabset (see
Figure 3-4
)
The ICS-2100 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.
