Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available. Find the best Raman spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.PolymersPolymers are large molecules made up of many repeat units. Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.SpectroscopySpectroscopy is a technique that analyzes the interaction of light with matter to study molecular properties, concentrations, and structural information. Widely used in chemical, pharmaceutical, and environmental analysis, spectroscopy offers insights into molecular composition and helps identify unknown compounds. It plays a key role in quality control, research, and diagnostics. Browse our peer-reviewed product directory to compare spectroscopy tools, read reviews, and get prices directly from manufacturers.
