Pressure Transducer
The pressure transducer measures the system backpressure.
Leak Sensor
The leak sensor is installed in the drip tray at the bottom of the component
panel. If liquid accumulates in the tray, an error message is logged in the
Chromeleon Audit Trail and displayed on the LCD touch screen.
Pump Heads
The ICS-2100 includes a dual-piston serial pump. The flow rate can be set
to 0.00 mL/min or to between 0.05 and 5.00 mL/min. However, for
optimum performance, set the flow rate to between 0.40 and
2.00 mL/min. Setting the flow rate to 0.00 mL/min turns off the pump.
See Section 2.4.3
for details about the pump.
Injection Valve
The injection valve is a six-port, electrically-activated Rheodyne valve. A
25-μL sample loop (P/N 042857) is installed on the valve at the factory.
See Section 2.4.6
for details about valve operation.
Auxiliary Valve (Optional)
The auxiliary valve is a two-position, electrically-activated Rheodyne
valve (6-Port Valve Kit, P/N 069472; 10-Port Valve Kit, P/N 069473).
See Section 2.4.6
for details about valve operation.
DS6 Heated Conductivity Cell
The flow-through conductivity cell measures the electrical conductance
of analyte ions as they pass through the cell. A heat exchanger inside the
cell regulates the temperature, which can be set to between 30 and 55 °C.
For optimum performance, set the temperature to at least 7 °C above the
ambient temperature and 5 °C above the column oven temperature. See
Section 2.4.10
for details about the cell.
