Method and device for preparing substances for qualitative and quantitative analyses

摘要

A method and a device for preparing a qualitative and quantitative analysis of samples are presented. The device affords the possibility of delimiting and isolating a specific region of a solid or liquid sample. A liquid, e.g. a solvent or extracting agent, is added in the delimited and isolated region. Thereafter the created mixture of substance and liquid is, in a plug-shaped fashion, pressed out of the closed region by means of a neutral liquid or the same liquid, and supplied to the measuring instrument in the form of a highly concentrated solution.

1. A method for preparing a qualitative and quantitative analysis of a substance, comprising:
isolating a sample including the substance embedded in a matrix, the matrix consists of insolubly solid or soluble components, in a completely closed-off and sealed cavity by clamping a plate containing the sample between sealing edges of a head and a counter head, said plate arranged between said head and counter head; bringing said sample into contact with a liquid supplied by a supply line, wherein said liquid at least partially flows through said sample; and supplying at least a portion of the substance, as a specimen, to a measuring instrument via a discharge line.
