Quantitative analysis of the composition of dental alloys was attempted by means of inductively coupled plasma emission spectrometry. Small amounts of the alloys were sampled as specimens, which weighed 2, 4, 8, 16, 32, 64, 120 and 240 mg. Each specimens was dissolved in nitric acid or aqua regia solution. The specimens examined were 20 carat gold alloy, 12 percent content gold-palladium-silver-copper system alloy, indium-silver system alloy, chromium-nickel system alloy, and chromium-cobalt system alloy. Results are as follows 1. In the solutions, in which more than 64mg of the alloys were dissolved, the total weight of detectable elements was equal to the original weight of the specimen, while in the solutions dissolving less than 32mg of the alloys, it was less than the original weight. 2. In the solutions dissolving more than 8mg of the alloys, the content of each element calculated from the detected values was the same with that obtained in the solution dissolving more 64mg of the specimen. It is concluded that more than 64mg of samples was necessitated to obtain the same accuracy for infinitesimal elements of the alloys.
