techniques: X-Ray Techniques

20X-ray systems can provide detailed information about sample structure and composition. Our facilities offer a huge array of techniques to probe samples from physical and life science applications. Our tools can be used to solve crystal structures, analyze surfaces and provide compositional information.

X-RAY PHOTOELECTRON SPECTROSCOPY (XPS)

X-ray photoelectron spectroscopy (XPS) is a powerful surface analysis technique that can provide quantitative information about elemental composition as well as chemical bonding. Our tools are also equipped with sputtering capabilities and angle-resolved measurements for depth profiling, ultraviolet photoelectron spectroscopy (UPS) and sample heating and cooling.

Our current range of XPS instruments can be found in our KECK-II Facility.

X-RAY DIFFRACTION (XRD)

X-ray diffraction (XRD) is a bulk measurement technique that can provide structural, chemical, and phase information of crystalline materials. By matching experimental data to spectral signatures, our instruments can be used to determine the identity of a variety of samples.

Our current range of XRD instruments can be found in our Jerome B. Cohen X-Ray Diffraction Facility and IMSERC Facility.

SMALL & WIDE ANGLE X-RAY SCATTERING

Small and wide angle (SWAXS) x-ray scattering is a specialized x-ray technique that can provide structural information with high spatial resolution. Through this technique, our facility provides a method for acquiring structural information from samples that are traditionally challenging to probe using x-ray techniques, such as nanoscale and macromolecular structures.

Our current range of SWAXS instruments can be found in the Jerome B. Cohen X-Ray Diffraction Facility 

X-RAY FLUORESCENCE (XRF)

For chemical and compositional identification of materials, such as ceramics and metals, x-ray fluorescence is a particularly useful technique. Using this non-destructive characterization technique, the elemental constituents can be mapped across the sample, making it a valuable method for analyzing artwork and geological structures.

Our current range of XRF instruments can be found in the Jerome B. Cohen X-Ray Diffraction Facility.
