Measurement of Total Calcium in Serum by Atomic Absorption Spectrophotometry, with Use of a Strontium Internal Reference

Abstract: A method for total calcium in serum was optimized, a dual double-beam atomic absorption spectrophotometer being used, with strontium as an internal reference. The effect of HCl and lanthanum concentrations on the signals of both calcium and strontium was determined. The final analysis was unaffected by known sources of interference in serum at a 50-fold dilution of serum in 50 mmolar HCl containing 10 mmol LaCl3 and 0.12 mmol of SrCl2 per liter. Within-run precision for 30 replicate analyses performed during 3… Show more

“…Aliquots were taken for the measurement of both calcium concentration and Ta-radioactivity. Calcium concentration was analyzed by an atomic absorbtion spectrophotometer (Unicam SP90A) applying the method of Pybus et al (1970). '"Ca-activity was determined by the liquid scintillation counter by setting the discriminators to the energy level where no "-activity was present.…”
