✦ Synopsis

A simple and rapid method is described for the determination of l-40 pg g" calcium in steels by electrothermal atomic emission spectrometry. The sample is dissolved in nitric acid and does not need preconcentration.

The use of a recessed platform is shown to improve reproducibility and sensitivity in the determination of calcium. A similar procedure for the determination of barium (< 1 rg g') in steel is described. aOn leave from the Department of Analytical Science, Beijing Mining and Metallurgical Research Institute, Xizhimen, Beijing (China).
