Self-Correcting Method for the Measurement of Free Calcium and Magnesium Concentrations by 1H NMR

A method for the direct measurement of free Ca2+ and Mg2+ concentrations in the range of 1–100 mM by NMR spectroscopy is demonstrated. The method automatically corrects for the effect of ionic strength on the activity of the species in solution and works satisfactorily even when significant concentr...
