A simple controlled spark apparatus, based on the Maresca-Simons-Raiskij scheme, was constructed. In spite of its simplicity, experiments have given very high accuracy of analytical results. Several factors which may influence the reproducibility of the analytical results were investigated using Industrial Research Quantometer (A. R. L.) and ordinary photographic procedure. As a results, reproducibility of 2.4% expressed as standard deviations was obtained for the analysis of Ni in nickel-steel, wheseas 3.5% had obtained using high voltage spark supplied from High Precision Source Unit. This improvement in accuracy however, may mainly due to the difference of vaporization processes, although the stability of this apparatus had been clearly indicated by the stability of so-called arc to spark line ratio particularly.<BR>Low cost and easy maintenace are also the excellent features of this apparatus.
