Chemical analysts who use spectroscopy to extract molecular information from samples have been following the developments in Raman instrumentation. Vibrational spectroscopy provides detailed molecular information, but Fourier-transform IR has been much easier to use than Raman. Now that Raman equipment is smaller, cheaper, faster, and easier, analysts are interested. Columnist Fran Adar will discuss why.

Columnist Fran Adar discusses surfaced-enhanced Raman scattering (SERS). The phenomenon is described and the enhancement factors that make it so attractive for analytical purposes are pointed out. In particular, she reviews the state-of-the-art from the point of view of the instrumentation and the robustness of the measurements.

Raman microscopy was developed as a tool for microanalysis complementary to the electron microscope, which enabled identification of the elements in a microspot. The first realization for Raman imaging was implemented using a nonconfocal optical method. Subsequently, a confocal scheme was developed, which provided better contrast in the Raman image. A number of successful examples from pathology, pharmaceutical analysis, and geology will be shown.
