Raman Spectroscopy (Raman)
Overview
At Outermost Technology, we proudly offer Raman Spectroscopy as a powerful analytical technique within our comprehensive suite of services. Raman Spectroscopy harnesses the unique phenomenon of inelastic scattering, where laser light interacts with molecules and materials, providing invaluable insights into their chemical composition, molecular structure, and vibrational properties.
This non-destructive technique operates by directing a monochromatic laser beam onto a sample. As the laser light interacts with the sample, a small fraction of the scattered light undergoes Raman scattering. This phenomenon results in frequency shifts in the scattered light, creating a distinctive spectral fingerprint that is unique to the chemical bonds and molecular vibrations within the sample.
By analyzing the Raman spectrum, we can precisely identify the substances present, determine their chemical compositions, and unveil structural details. Raman Spectroscopy finds diverse applications, from identifying unknown substances and studying crystalline structures to characterizing biological samples and monitoring chemical reactions.
Our expertise in Raman Spectroscopy empowers researchers, industries, and innovators to delve into the intricacies of matter, unlocking a deeper understanding of their materials and compounds. Whether you’re exploring the world of chemistry, materials science, or biotechnology, Raman Spectroscopy provides a powerful lens to unravel the mysteries of the microcosm.
