Location: Universidad Pública de Navarra, Edificio Jerónimo de Ayanz, Sala blanca sótano
Associated technology services: The device directs a laser beam onto a sample. Most of the light is scattered without changing energy, but a small fraction undergoes Raman scattering. This signal contains information related to the chemical bonds and molecular structure of the material. The spectrometer records this signal and generates a Raman spectrum, which acts somewhat like a fingerprint of the material. Applications include: identifying unknown substances and materials; determining the chemical composition of a sample; differentiating materials that appear visually identical; studying crystalline structures and phases; detecting chemical or structural changes; analyzing stresses and strains in certain materials; studying polymers, minerals, semiconductors, metals, ceramics, pigments, pharmaceuticals, etc.; and analyzing very small samples without destroying them. Because it is confocal, three-dimensional information can be obtained through 3D Raman mapping.
Application sector: Polymer, pharmaceutical, pigment and paint, electronics, sensor, semiconductor materials, and currency industries. Also involved in forensic investigations, including the study of counterfeit currency, works of art, and general studies of cultural heritage.
