Short Description

The Raman microscope DXR from the company Thermo Fisher Scientific allows for the Raman spectroscopic characterization of both macroscopic samples and microscopic samples of inorganic or organic nature.

The Raman spectroscopic measurements can be performed polarization-dependent with regard both to excitation light and scattered light. The available laser wavelengths for excitation of the samples are 455 nm, 532 nm and 785 nm.

The automated microscope stage allows Raman mapping or Raman imaging, i.e. the pointwise recording of Raman spectra as a function of the area of a sample. The minimum step size in X, Y, and Z direction is 1 μm.

Methods & Expertise for Research Infrastructure

Raman spectroscopy is used for the characterization and analysis of solid, liquid and gaseous samples (both organic and inorganic) within the fields of physics, chemistry, materials science, biosciences and forensics. The samples can usually be examined non-destructively.

The information obtained by Raman spectroscopy is based on the vibrations of atoms bound within molecules or crystal lattices, whereby these vibrations can be influenced by intramolecular and intermolecular interactions, as well as by external parameters, e.g. the thermodynamic state (temperature, pressure, concentration).

The spectra show, on the one hand, characteristic frequencies, so-called group frequencies of functional groups within molecules, on the other hand a fingerprint region, which is characteristic of the investigated molecule and is used to identify substances.
