Eluent Valve
The eluent valve controls the flow from the eluent reservoir. It opens
automatically when the pump is running and closes when the pump is off.
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 reported in
Chromeleon and the Alarm LED flashes.
Pump Heads
The ICS-1000 includes a serial isocratic dual-head pump. The flow rate
can be set to 0.00 and to between 0.05 and 5.0 mL/min. However, for
optimum performance, set the flow rate to between 0.4 and 2.0 mL/min.
Setting the flow rate to 0.00 turns off the pump. See Section 2.4.3
for
details about the pump.
Pressure Transducer
The pressure transducer measures the system backpressure.
Injection Valve
The injection valve is a six-port, electrically-activated valve. A 25-µL
sample loop (P/N 042857) is installed on the valve at the factory. See
Section 2.4.4
for details about valve operation.
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.
Column Heater (Optional—Not Pictured)
The column heater controls the temperature of the separator and guard
columns. The temperature can be set to between 30 °C and 60 °C and it
must be set at least 5 °C above the ambient temperature. See Section 2.4.5
for details about the column heater.
