X-ray photoelectron spectroscopy


The XPS is an analysis technique that provides quantitative and chemical state information from the surface of the material (typically with depths of analysis around 10nm). By irradiating the sample with an X-ray source, photoelectrons are emitted from the surface and its energy is analyzed in order to determine the elemental identity, chemical state and quantity of an element. Bulk samples and powder samples can be analyzed in the system. Our equipment is an ultra-high vacuum multi-chamber system by SPECS.
