LabRAM HR800 is a high-resolution µ-Raman system, which can be used to get detailed information about the chemical composition, crystal structure, and the nature of chemical bonds
Applications of µ-Raman spectroscopy are for example
- chemical analysis of materials
- structural analysis of molecules
- determination of phases and compositions of compounds
- analysis of mechanical stress
- characterization of thin films
- characterization of polymers
- characterization of geological samples
- characterization of micro and nanostructures (carbon nanotubes etc.)
In µ-Raman measurement the spot size of the laser beam is kept very small, only a few micrometers in diameter. This makes it possible to get very accurate spatial information about the sample under investigation. It is also possible to scan the beam across the sample surface and to get information about the changes in the chemical compositions or phases of the sample. Also, information considering the mechanical stresses of the sample can be obtained. Raman spectroscopy can be used in analysis of both organic and inorganic materials. Samples can be either solid or liquid.
