[Determination of the cations concentrations in the dialysis fluid by an atom absorption spectrometer].
The atom absorption spectrometer is introduced to determine the cation concentrations such as potassium, sodium, calcium and magnesium in the dialysis fluid. They are accurately determined by proper preparation and correct dilution ratio under the optimized measuring conditions. Compared with the current arbitrate methods (EDTA titration determination of calcium and magnesium), it supplements the methods of international and industrial standards for determination of cations.
