Flow Description for RFIC-ER Mode

• Eluent from the eluent reservoir flows first through the pump degas

assembly (if it is installed) and then through the eluent valve

to the pump.

The eluent is then pushed through the pressure transducer

, which measures

the system pressure.

• From there, the eluent is pushed through a pulse damper, which smooths

minor pressure variations from the pump to minimize baseline noise. The

eluent then flows through the ER1 column

 and into the injection valve .

• After sample is loaded into the sample loop and the injection valve is

toggled to the Inject position, eluent passes through the sample loop.

• If the optional column heater is installed, the eluent/sample mixture is

pumped through the heat exchanger

, which heats the mixture to the column

heater temperature.

• The mixture then goes to the guard and separator columns and through the

suppressor .

• From the suppressor, the mixture flows through the cell , where the analytes

are detected. A digital signal is sent to Chromeleon software. Analog output

can be collected simultaneously.

• Finally, the mixture flows out of the cell, through the ER2 column , and is

then recycled back into the suppressor.

• From the suppressor, flow moves to the ER3a and ER3b columns, which

remove contaminants from the eluent.

• The ERC 10 monitors the eluent for gas and shuts down the pump if the gas

exceeds a pre-defined limit.

• Finally, the output from the ERC 10 is recycled back to the eluent bottle.
