Abstract
A method is disclosed for determining calcium ion content of serum which comprises calibrating a potentiometric analytical system with calcium standards having a solution containing both TRIS and BisTRIS at a pH of 7.5. The serum sample is diluted with a silicone oil/water emulsion which may further contain a protein complexing agent such as iron, zinc, cadmium, nickel or copper. Measurement is then carried out on the diluted serum sample.
