Mossbauer spectrometer

Application:

The Mossbauer effect can be used to study the hyperfine interactions between atomic nuclei and their surrounding environment

Capable of measuring the valence state, phase and content of iron atoms and atoms related to iron atoms

>It is used to study various sample types (including nanoscale and bulk materials) and specific nuclei.
>Capable of analyzing detailed physical and chemical structural information.
>Non destructive analysis techniques.
>Capable of analyzing samples with low concentrations of specific nuclei.

>Only applicable to solid samples (also suitable for frozen liquids).

>We need a radioactive source.
