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 DS5 Detection Stabilizer (P/N 067761). For details
about the conductivity cell and DS5 Detection Stabilizer, see
Section 2.3.1 .
MMS™ 300 MicroMembrane Suppressor
The MMS 300 suppressor reduces the eluent conductivity and enhances
the conductivity of the sample ions, thereby increasing detection
sensitivity. For details about the MMS 300 suppressor, see
Section 2.3.4 .
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.
Pressure Transducer
The pressure transducer measures the system backpressure. See
Section 2.3.2 for details about the pressure transducer.
Pump Heads
The ICS-900 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 details about the pump, see
Section 2.3.1 .
Injection Valve
The injection valve is a six-port, electrically-activated valve. For details
about the injection valve, see
Section 2.3.3 .
