Dispersive Raman spectrometers utilize a form of vibrational spectroscopy to provide information regarding molecular structure.  Raman spectra are used for identification and quantification of both organic and inorganic materials and are very sensitive to minor changes in molecular structure. The Renishaw system has many applications in the pharmaceutical, forensic, and semiconductor fields, and features specialized sampling options for many applications in these areas.  Sampling is nondestructive and can often be performed directly through glass or plastic packaging, providing an excellent solution when non-invasive sampling is required.  If you are interested in using or training on the Renishaw system, please contact matfab-staff@uiowa.edu.

Instrument Specifications
