The Use of Raman Spectroscopy in the Pharmaceutical Industry – from Discovery to the Warehouse
Raman spectroscopy has been utilized in the pharmaceutical community for years. Raman works best for raw material identification, polymorphic studies and high throughput screening. However, many active ingredients exhibit fluorescence precluding the use of Raman. A new hand-held Raman spectrometer is now available for users to analyze samples utilizing new patented fluorescence mitigation methods. This new spectrometer has a wide spectra range, high spectral quality for optimizing the analysis, resulting in virtual elimination of false positive/false negative test results.

Using Spectroscopy to Measure Geochemical Transformations of Gypsum for Ca-Sulfate Detection on Mars
May 2nd 2025Research was conducted exploring the dehydration pathways of gypsum (CaSO₄·2H₂O) and its interactions with chloride (Cl) salts under a range of thermal and environmental conditions relevant to Earth and Mars.Spectroscopy spoke to Merve Yeşilbaş, corresponding author of a paper based on this work (1), about the research.
The Role of LIBS in ChemCam and SuperCam: An Interview with Kelsey Williams, Part III
May 2nd 2025In this extended Q&A interview, we sit down with Kelsey Williams, a postdoctoral researcher at Los Alamos National Laboratory (LANL), who is working on planetary instrumentation using spectroscopic techniques such as laser-induced breakdown spectroscopy (LIBS) and laser ablation molecular isotopic spectrometry (LAMIS). In Part III, Williams goes into detail about ChemCam and SuperCam and how LIBS is used in both these instruments.
