•
Eluent from the pump 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 loop.
•
The eluent/sample mixture is pumped first through a temperature
stabilizer (analytical IC only), through the guard and separator
columns
, and then through the suppressor .
•
From the suppressor, the mixture flows through a CRD (if installed) to
the cell , where the analytes are detected. A digital signal is sent to
Chromeleon.
•
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
