Tuesday, Nov. 14; 8:30am – 5:00pm
Alexander Rzhevskii, Thermo Fisher Scientific, Tewksbury, MA
The purpose of this course is to familiarize a wide circle of engineers and researchers with the fundamentals and applications of modern Raman microscopy including confocal Raman imaging. The basics of Raman spectroscopy, instrumentation, principles of operation, and the main characteristics of Raman spectrometers and microscopes will be presented in the course. Examples of the application of Raman microscopy for the characterization of spatial structure, composition, and properties of “real world” samples and objects with the emphasis on polymer, pharmaceutical, biological cosmetic, foodstuff, and plant analytical studies will be provided. A hands-on demonstration of a Raman microscope will follow the lecture. Bring your challenging samples and uncover their composition and structure!
WHO SHOULD ATTEND
This course is intended for a wide circle of experimenters from a diversity of disciplines and different backgrounds, who are using or intending to use Raman spectroscopy in their analytical work. The course will be beneficial for novice Raman spectroscopy users and serve as a reference and systemizing resource for spectroscopists with the background in vibrational spectroscopy.
