WebOur Instrument and its Capabilities. XPS is a spectroscopic technique to quantitatively measure the elemental compositions and chemical and electronic states of the elements of a material, including their bond energy. To obtain the XPS spectra, the sample is irradiated with a beam of X-rays. The kinetic energy and number of electrons escaping ... WebUnfunded USC users may need XPS analysis of a limited number of samples to support the development of funded projects or to provide key data for a timely publication. Unfunded USC users must submit a brief (1 page maximum) request for free analyses to Dr. Mike Matthews, Associate Dean for Research and Graduate Education.
