Apparatus and method for simultaneous sampling of material at multiple depths

Abstract:

Embodiments of the present invention relate to a sampling apparatus having one or more support structures and two or more sampling molds operatively coupled to the one or more support structures. The two or more sampling molds may be sealed or unsealed. The sampling apparatus is pressurized with a gas and immersed in the molten metal. The two or more sampling molds become unsealed when the mold stops at least partially melt. When the sampling apparatus is depressurized the one or more unsealed sampling molds capture one or more molten metal samples. The sampling apparatus is removed from the molten metal and the samples are removed from the sampling molds and analyzed.
