Thermofisher K-Alpha

Description

X-ray Photoelectron Spectroscopy (XPS) is a widely used surface analysis technique that provides valuable quantitative and chemical state information from the surface of materials. XPS is used for analyzing the surface composition and chemical bonding states of a wide variety of materials, including metals, polymers, semiconductors, and ceramics.
