Determination of Calcium in Biological Fluids

Stable Calcium Isotopes as Tracers in Studies of Mineral Metabolism

“…Titrations dependent upon visual end-points (Greenblatt and Hartman, 1951;Golbyn et al, 1957;Hildebrand and Reilley, 1957;Bachra et al, 1958;Baron and Bell, 1959;Mori, 1959;Lewis and Melnick, 1960;McAllister and Yarbo, 1960;Pappenhagen and Jackson, 1960;Fingerhut and Miller, 1963), and potentially more precise but tedious photometric titrations (Kilbrick et al, 1952;Fales, 1953;Lehmann, 1953;Buckner and Shively, 1955;Eldjarn et al, 1955;Homer, 1955;Van Schouwenberg, 1960) have been followed by other methods of end-point detection. Bett and Fraser (1959) observed rate of change of galvanometer deflection, as did Foss and Andersen (1958).…”

Vitamin-D-resistant Osteomalacia

“…The main chemical methods used were as follows. Serum calcium: Greenblatt and Hartman (1951); serum and urinary inorganic phosphate: King (1951); urinary, faecal, and food calcium: Jackson and Irwin (1958); nitrogen: micro-Kjeldahl; inulin: Roe et al (1949); potassium: flame photometer (Jackson and Irwin, 1958).…”
