2.2 Flow Schematics
The following figures illustrate the liquid flow path through a Dionex ICS-1100
when using suppression in autorecycle mode. Two configurations are shown:
•
Figure 2-7 illustrates the liquid flow path through components when
performing conventional ion chromatography.
•
Figure 2-8 illustrates the liquid flow path through components when operating
in the RFIC-ER mode.
Flow Description for Standard Configuration
•
Eluent from the eluent reservoir

flows first through the pump degas
assembly (if it is installed) and then through the eluent valve

to the pump

.
The eluent is then pushed through the pressure transducer

, which measures
the system pressure.
•
From there, the eluent is pushed through a pulse damper

, which smooths
minor pressure variations from the pump to minimize baseline noise. The
eluent then flows into the injection valve

.
•
After sample is loaded into the sample loop

and the injection valve is
toggled to the Inject position, eluent passes through the sample loop.
•
If the optional column heater is installed, the eluent/sample mixture is
pumped through the heat exchanger

, which heats the mixture to the column
heater temperature.
•
The mixture then goes to the guard and separator columns

and through the
suppressor

.
•
From the suppressor, the mixture flows through the cell , where the analytes
are detected. A digital signal is sent to Chromeleon software. Analog output
can be collected simultaneously.
•
Finally, the mixture flows out of the cell and is recycled back into the
suppressor, where it is used as the water source for the regenerant chamber.
Flow is then routed to waste
.
