Deionized water from the reservoir

n

flows first through the pump degas 

assembly and then through the eluent valve

o

 to the pump

p

. The water is 

then pushed through the pressure transducer

q

, which measures the system 

pressure. From there, the water flows through a pulse damper

r

, which 

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

•

Water then flows into the EluGen cartridge (EGC)

s

, which generates the 

programmed concentration of carbonate eluent. Eluent exits the cartridge and 
flows through the EGC degas tubing assembly

t

. Eluent then goes to the 

EGC CO

3

 Mixer

u

 (to ensure a homogenous eluent concentration), and then 

on to the injection valve

v

.

•

After sample is loaded into the sample loop

w

 and the injection valve is 

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

•

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.

•

The mixture flows out of the cell and is recycled back into the suppressor

, 

where it is the water source for the regenerant chamber.

•

Regenerant waste from the suppressor is directed back to the EGC degas 
tubing

, where any released hydrogen or oxygen gas is removed before it is 

sent to the gas separator assembly and then to waste

.
