Conductivity Cell
The flow-through heated conductivity cell measures the electrical
conductance of analyte ions as they pass through the cell. A heat
exchanger inside the cell regulates the temperature to 40 °C (104 °F). The
cell is housed inside a Thermo Scientific
Stabilizer (P/N 067761). For more information about the conductivity cell
and Dionex DS5 Detection Stabilizer, see
Suppressor
The suppressor reduces the eluent conductivity and enhances the
conductivity of the sample ions, thereby increasing detection sensitivity.
The Thermo Scientific
(Dionex CRS

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 particulates that might damage the separator
column.
Pressure Transducer
The pressure transducer measures the system backpressure. For more
information about the pressure transducer, see
Pump Heads
The Dionex Easion includes a dual-piston serial pump. The flow rate can
be set from 0.01 mL/min to 5.00 mL/min. However, for optimum
performance, set the flow rate to between 0.20 and 3.00 mL/min. Setting
the flow rate to 0.00 mL/min turns off the pump. For more information
about the pump, see
Injection Valve
The injection valve is a six-port, electrically-activated valve. For more
