ABSTRACT:
A system is disclosed for analyzing molten metal which comprises removing a sample of metal from a source of molten metal; dissolving the sample in a solvent; and analyzing the dissolved sample to determine the contents of the molten metal. In a preferred embodiment, the sample is removed from the molten metal as solid particles in a sampling zone, conveyed in a fluid to a dissolution zone where a known quantity is dissolved for subsequent spectral analysis, and the resulting solution is then passed to a spectral analysis zone.
