Festkörperprobe

Festkörperprobe is a German term that translates to "solid sample" or "solid-state sample" in English. It refers to a sample of material that is in a solid state, as opposed to a liquid or gaseous state. In scientific contexts, particularly in analytical chemistry and materials science, a Festkörperprobe is the material being analyzed or tested. The methods used to analyze a Festkörperprobe depend heavily on the nature of the material and the properties being investigated.

Common techniques for analyzing Festkörperproben include spectroscopy, X-ray diffraction, microscopy, and various thermal analysis methods. For example, X-ray diffraction (XRD) is frequently used to determine the crystalline structure of a Festkörperprobe. Spectroscopy, such as infrared (IR) or Raman spectroscopy, can provide information about the molecular composition and functional groups present in the solid. Microscopy techniques, like scanning electron microscopy (SEM) or transmission electron microscopy (TEM), allow for the observation of the sample's surface morphology and internal structure at high magnifications.

The preparation of a Festkörperprobe is a crucial step before analysis. This can involve grinding, polishing, sectioning, or dissolving the sample, depending on the analytical technique. The goal of sample preparation is to ensure that the sample is in a suitable form for measurement and that any potential interfering factors are minimized. The term Festkörperprobe is broad and encompasses a wide range of solid materials, including metals, ceramics, polymers, minerals, and biological tissues.
