•
Eluent from the pump
•
After sample is loaded into the sample loop
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
•
From the suppressor, the mixture flows through a CRD
the cell
Chromeleon.
•
Finally, the mixture flows out of the cell and is recycled back into the
suppressor
