Raman Spectrometry

Raman Spectroscopy (Raman Analysis) enables the determination of chemical structure and the identification of compounds using vibrational spectroscopy. Raman has better spatial resolution than FTIR and enables the analysis of smaller dimensions, down to the 1µm range.

Raman is an ideal technique for the qualitative analysis of organic and/or inorganic mixed materials and can also be employed for semi-quantitative and quantitative analysis. It is often used to:

• Identify organic molecules, polymers, biomolecules, and inorganic compounds both in the bulk and in individual particles
• Imaging and depth profiling is used to map the distribution of components in mixtures, such as drugs in excipients, tablets, and drug-eluting stent coatings
• Determine the presence of different carbon types (diamond, graphitic, amorphous carbon, diamond-like carbon, nanotubes, etc.) and their relative proportions
• Determine inorganic oxides and their valence state
• Measure the stress and crystalline structure in semiconductor and other materials

EAG offers our customers Raman services to analyze defects, particles and contaminants, identify materials in small areas, and to measure stress. The resulting data helps our clients resolve problems quickly, reduce cycle times, and improve production processes. We believe that no competing lab can match the skill set and experience of our staff. Plus, you can count on fast turnaround times, accurate data, and person-to-person service, ensuring you understand the information that you receive.
