8.6 Principle of electrolyte measurement
8.6.1 Principle
Internal standard solution is firstly added into the instrument reaction
cuvettes, and assimilates it and discharges it into the Na, K, and Cl electrode
solution line through the SIP injection pump to measure its electrode potential
which is relative to reference electrode potential. Then needle draws the
samples and then sample is diluted then added to the reaction cuvette. To test
liquid electric potential mixed with electric potential, the calculation of
the concentration comes out.
8.6.2 Principle of generating electrode potential
Electrode potential is obtained by Nernst's formula.
