title: Determination of inorganic phosphorus using a centrifugal analyzer.
abstract: A method involving the molybdenum blue reaction for measurement of serum phosphorus using a centrifugal analyzer is described. The need to measure a separate serum blank is eliminated by measuring the rate of color development compared to that of a known standard. The procedure which uses o-phenylenediamine as a reductant is precise and compares well with a continuous flow automated procedure.
