Transmission Raman Offers Improved Quantitation of Pharmaceutical Solids
June 1st 2009Manufacturing control of pharmaceutical solids requires routine measurement of content uniformity. Because of the high information content in Raman spectra, it has been considered a candidate technology for making these measurements.
Analysis of Multicomponent Polymer Blends with Confocal Raman Imaging and Atomic Force Microscopy
June 1st 2009Polymer blends are designed to address the needs of different industries, and in many cases the relationship between structure, morphology, and material properties is indispensable for optimization of material design.
Combining Raman Spectroscopy and Differential Scanning Calorimetry
June 1st 2009Raman spectroscopy and differential scanning calorimetry (DSC) are powerful techniques in their own right. Combining the two techniques allows one to combine the chemical and structural information of Raman with the temperature and energetic information of DSC. This allows us to develop a greater understanding of the material. Applications from polymeric and pharmaceuticals are discussed as examples of how this can help the analyst.
Raman Spectroscopy as a Rapid Characterization Tool for Heterogeneous Solids
June 1st 2009There are many situations in which it would be highly desirable to apply the benefits of Raman to larger volumes of solid material such as powders, tablets, and composites. Raman benefits such as minimal sample preparation, the ability to provide rich information on both organics and inorganics, and its ability to measure through glass and plastic packaging make it highly amenable to these kinds of samples.
