Suppressor
The suppressor reduces the eluent conductivity and enhances the
conductivity of the sample ions, thereby increasing detection sensitivity.
Either a Dionex AES
™
Atlas Electrolytic Suppressor, Dionex SRS
™
Self-
Regenerating Suppressor, or Dionex MMS
™
MicroMembrane
™
Suppressor can be used with the Dionex ICS-1100. See Section 2.4.7 for
details about the suppressor.
Separator and Guard Columns
Both the separator and guard columns are packed with resin and perform
the separation of the sample ions. The main function of the guard column
is to trap contaminants and remove particulates that might damage the
separator column.
Column Heater (Optional)
The column heater controls the temperature of the separator and guard
columns. The temperature can be set to between 30 and 60 °C; however,
it must be set to at least 5 °C above the ambient temperature. See
Section 2.4.6 for details about the column heater.
Eluent Valve
The eluent valve controls the flow from the eluent reservoir. The eluent
valve opens automatically when the pump is started and closes when the
pump is turned off.
Tubing Chases
The upper tubing chase routes tubing from the top cover to the component
panel. The lower tubing chase routes tubing from the component panel,
through the interior of the Dionex ICS-1100, to the rear panel. It also
routes tubing from the RFIC-ER compartment, through the interior of the
Dionex ICS-1100, to the component panel.
