Raman Spectroscopy Lab Services and Applications
In the Raman Spectroscopy Laboratory at MVA Scientific Consultants, our experts provide a wide spectrum of Raman analysis and Raman mapping applications. Raman analysis is an ideal technique for the qualitative and semi-quantitative analyses of organic and/or inorganic mixed materials. Samples analyzed by Raman spectroscopy include proteins, polymers, pharmaceuticals, minerals and other inorganics.
Raman applications and services offered by MVA:
- Identification of organic and inorganic materials, polymers, and biomolecules in particles, defects and bulk materials
- The determination of the presence of different carbon types including diamond, graphitic, nanoparticles and nanotubes, diamond-like carbon and amorphous carbon
- Measurement of crystalline structures and stresses in semiconductors and polymers
- Raman mapping analysis of the distribution of components in mixtures such as active pharmaceutical ingredients in excipients, tablets and drug-eluting stent coatings
