Ellipsometry - AAU
homes.nano.aau.dkEllipsometry is generally a non-invasive, non-destructive measurement technique to obtain optical properties of a sample material by means of the reflected light waves. The technique measures a relative change in polarization and is therefore not dependent on absolute in-tensity as long as the absolute intensity is sufficient.
THEORY OF XRF - Purdue University
www.chem.purdue.eduThe method is fast, accurate and non-destructive, and usually requires only a minimum of sample preparation. Applications are very broad and include the metal, cement, oil, polymer, plastic and food industries, along with mining, mineralogy and geology, and environmental analysis of water a nd waste materials.
