Blood serum is analyzed for Na, K, Ca, Mg, Fe, Cu, and Zn by using a simultaneous, multielement, atomic absorption spectrometer with a continuum source (SIMAAC). Because of the extended range capabilities of the SIMAAC system, analyses can be carried out on a single 5-fold dilution. Standards and samples are matched in appropriate concentrations for the major, minor, and trace elements. The SI-MAAC results show excellent agreement with the certified values for the National Bureau of Standards serum reference material and the manufacturer's values of a commercially available calibration material, Cation-Cal (American Dade). The relative standard deviations of day-to-day precision studies range from 1.4% for Na to 11.1% for Fe. Good correlations are obtained between the values obtained by SIMAAC and comparative clinical methods. 20 references, 2 figures, 4 tables.
