X-Ray Photoelectron Spectroscopy (XPS) @ University of Limerick Bernal Institute (UL)

Institution University of Limerick Bernal Institute (UL)
County Limerick
Technique Category Spectroscopy
Technique X-Ray Photoelectron Spectroscopy (XPS)

Basic Capabilities

Identification and quantification of  elements and the chemical binding states of these elements in the top 3-10 nm of a surface. It also allows 2D chemical imaging with a spatial resolution of ~ 3 µm


Equipment Make Kratos
Equipment Model Ultra DLD


Advantage of Technique/Equipment

Sensitive to the top ~10 nm, can detect all elements except H and He, sensitive to differences in chemical environments, quantitaive without using standards, applicable to conducting and insulting samples

Limitations of Technique/Equipment Samples need to be vacuum compatible, detection limit~ 0.1atomic %
