Surface Analysis

A Raman microscope is an analytical instrument that combines Raman spectroscopy with microscopy to provide detailed chemical and structural information about a sample at the microscopic level. It utilizes a focused laser beam to excite the sample, causing inelastic scattering of light (Raman scattering), which is then collected and analyzed to generate a Raman spectrum that provides a unique chemical fingerprint of the sample, allowing for the identification and characterization of various materials, including polymers, pharmaceuticals, and biological samples, with high spatial resolution. Our system has access to a 532 nm point laser and a 785 nm line laser. We have 5x, 20x and 50x focal objectives.

X-ray Photoelectron Spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is a surface-sensitive analytical technique used to determine the elemental composition, chemical state, and electronic structure of a material's surface. It involves irradiating a sample with a beam of X-rays and measuring the kinetic energy and number of electrons that escape from the top 1 to 10 nm of the material, providing quantitative information about the surface chemistry and allowing for the identification of chemical bonding states and oxidation states of elements present on the sample surface.
