sample preparation container for analysis, methods for preparing a sample for analysis, and system for automatically preparing a sample for analysis

摘要

The present invention provides a container and method for preparing a sample for analysis. The container comprises a cavity for receiving a sample, including a collecting material and a precious metal. The cavity is suitable for melting the sample and oxidizing the collecting material. The cavity comprises a first region defined by a porous material that is capable of absorbing the collecting material when oxidized and molten. the cavity comprises a second region defined by a material that is largely unable to absorb the molten and oxidized collecting material. The second region is capable of maintaining a molten sample volume. the container is disposed and the method is carried out such that when the sample has melted and shrunk due to absorption by the porous material of the first region, at least a portion of the remaining sample remains in the second region.
