Abstract: 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.

Abstract: A fully automatic extraction and analysis system for biologically active samples significantly simplifies the analysis of, for example, DMS samples and has significant advantages over the manual technology and the partially automated technology (punching out). The described extraction system is the first economical alternative to conventional blood analysis and supports the spread of said time-, cost-, and animal-saving technology in pharmacology and toxicology.
