ICS-1000 Ion Chromatography System Operator's Manual

2 • FeaturesEluent ValveThe eluent valve controls the flow from the eluent reservoir. It opensautomatically when the pump is running and closes when the pump is off.Leak SensorThe leak sensor is installed in the drip tray at the bottom of the componentpanel. If liquid accumulates in the tray, an error message is reported inChromeleon and the Alarm LED flashes.Pump HeadsThe ICS-1000 includes a serial isocratic dual-head pump. The flow ratecan be set to 0.00 and to between 0.05 and 5.0 mL/min. However, foroptimum 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 fordetails about the pump.Pressure TransducerThe pressure transducer measures the system backpressure.Injection ValveThe injection valve is a six-port, electrically-activated valve. A 25-µLsample loop (P/N 042857) is installed on the valve at the factory. SeeSection 2.4.4 for details about valve operation.Separator and Guard ColumnsBoth the separator and guard columns are packed with resin and performthe separation of the sample ions. The main function of the guard columnis to trap contaminants and remove particulates that might damage theseparator column.Column Heater (Optional—Not Pictured)The column heater controls the temperature of the separator and guardcolumns. The temperature can be set to between 30 °C and 60 °C and itmust be set at least 5 °C above the ambient temperature. See Section 2.4.5for details about the column heater.Doc. 031879-01 3/03 2-5
