Do you find you’re not getting the whole picture using your current testing methods to determine a material’s chemistry? Would a complete understanding of a material’s molecular structure aid in the development of a new product or determine the root-cause of a product failure during manufacturing? Incorporating Raman Spectroscopy into your testing methods can help to get the whole picture to find the answers you need.

Current methods for material analysis such as X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM) can provide elemental and chemical information about a material but have limitations when providing information about its molecular structure. This can create problems when analyzing materials with similar chemical compounds but different structural make-ups such as carbon. Raman not only has the ability to provide chemical information about a material, it also provides greater details about the structural properties; which is useful when analyzing materials whose molecules can exist in polymorphic forms.

Join Rebekah Leigh Byrne, Laboratory Manager at Gateway Analytical as she provides an overview of Raman spectroscopy and its usefulness to determine the molecular structures of various materials commonly found in the pharmaceutical and material science industries. Rebekah will provide attendees with applications studies demonstrating Raman’s ability to discriminate between the different crystal structures of carbon, as well as its ability to differentiate silica gel from glass. She will also discuss additional applications where Raman can be a useful tool during analysis.
