Abstract A rapid survey of the elements in biological materials, covering most of the elements in the periodic table, is possible by using available software for semi-quantitative analysis (SEMI-QUANT) by inductively coupled plasma-mass spectrometry. The procedure takes 5 min after sample preparation and gives results with a precision (CV) of approximately 20%. At a 10-fold dilution, 13 elements can be consistently and reliably detected in serum and 15 elements in whole-blood samples. At present the most important limitation of this method is mass overlap by polyatomic species for some elements of interest (e.g., Cr, Mn, and V). However, for the set of elements that can be reliably determined at endogenous concentrations, including Li, B, Mg, Fe, Cu, Zn, Rb, and Sr, the rapid scanning capability may be useful. Although matrix effects limit the direct interpretation of the semi-quantitative output, reasonable estimates of concentration are attainable by using matrix-matched standards or by adding a multielement standard to an aliquot from one sample in the set. We also present an example of determination of 25 elements in saliva from a patient with extensive dental work: Components of many of his dental alloys were readily identified. The method may also prove useful for screening multiple toxic exposures to heavier elements, such as Pb, Tl, Cd, and Hg.

A flow injection system incorporating a microcolumn of activated alumina was combined with inductively coupled plasma mass spectrometry for on-line trace enrichment and determination of uranium in surface waters and sea water. Deposition of uranium was effected with the use of a basic alumina microcolumn, and injection of nitric acid (250 μL, 2M) served to elute retained species to the ICP. A sample volume of 14 mL resulted in a preconcentration factor of 40, and precision at the 50-ng 1−1 level was 4.5% (RSD). The procedure was applied to mineral waters, river water, and sea water, and accuracy was assessed through either analysis of certified reference waters or recovery experiments.
