Abstract

Abstract An improved ultramicrospectrophotometric procedure for the rapid determination of magnesium in biological fluids has been developed. It employs the “Mann” dye, sodium 1-azo-2-hydroxy-3 (2,4-dimethylcarboxanilide)naphthalene-1(2-hydroxybenzene-4-sulfonate), and requires only 40 μl of sample. In contrast to titan yellow procedures the presence of gluconate does not interfere with the proposed method.
