X-ray Fluorescence and Raman Spectroscopy Help Uncover Archeological Facts
Solvent-free analysis can make it possible to perform chemical analysis of molecules that are difficult or impossible to solubilize and avoid chemical reactions that change the structure of certain molecules in solution. Spectroscopy recently spoke with Sarah Trimpin, an assistant professor in the Department of Chemistry at Wayne State University, about her work with solvent-free analysis and imaging mass spectrometry (MS).

Rapid Authentication of Genuine and Counterfeit Pharmaceuticals
Author: Mark Mabry, Dr. Claire Dentinger
Overcoming fluorescence interference in Counterfeit Pharmaceutical samples is achieved using a dispersive, dual wavelength Xantus®-2 portable Raman spectrometer, equipped with both 785nm and 1064nm laser excitation.

Observing Heterogeneous Catalysts While They Are Working: Operando Raman Spectroscopy
Operando means working, thus, this technique refers to the combination of a characterization study of the surface of a catalyst at the same time that the activity is being monitored. This approach, which permits the simultaneous characterization of both parameters in a single experiment, facilitates uncovering the relationships between structure and activity. Such information is critical to improving the performance and formulation of catalysts. We illustrate the possibilities of operando Raman spectroscopy with four examples. MORE »
