Notes for Generating Carbonate/Bicarbonate Eluent
If an EGC III K
2
CO
3
and an EPM III Electrolytic pH Modifier are installed
(EGC_1 and EGC_2, respectively):
1. Set EGC_1 Target Concentration to the concentration of K
2
CO
3
required for your application
2. Set EGC_2 Target Concentration to the concentration of KHCO
3
required.
The K
2
CO
3
cartridge generates the total of the two target concentrations and
the EPM modifies the total to achieve the K
2
CO
3
/KHCO
3
eluent mixture that
you require.
For example:
For a 3.50 mM K
2
CO
3
/1.00 mM KHCO
3
eluent, set EGC_1 to 3.50 mM and
EGC_2 to 1.00 mM.
The K
2
CO
3
cartridge generates 4.50 mM K
2
CO
3
(indicated in the Applied
Concentration field for the K
2
CO
3
EGC). The EPM modifies the 4.50 mM
K
2
CO
3
eluent to achieve the required 3.50 mM K
2
CO
3
/1.00 mM KHCO
3
mixture.
