X-ray Photoelectron Spectroscopy
X-ray Photoelectron Spectroscopy (XPS)
In Chemical Composition
Base Price: $365 per Sample

X-ray photoelectron spectroscopy (XPS) is a highly surface-specific chemical analytical technique used to probe the elemental composition and bonding states in the outermost 2-10 nm of a solid surface. To characterize composition as a function of penetration depth in the sample, depth-profiling tests can be performed to iteratively access sub-surface compositional layers.

STEM + Energy Dispersive Spectroscopy
STEM + Energy Dispersive Spectroscopy (STEM + EDS)
In Chemical Composition
Base Price: $1250 per Sample

TEM is the highest-resolution imaging technique available today. It is used to visualize sample features with atomic-level spatial resolution limits in order to characterize morphology of complex nanostructures. Different imaging modes on the TEM can target certain types of contrast: amplitude contrast (arising from atomic number and mass/thickness) phase contrast (from quantum phase shifting due to multiple scattered beams’ interference), diffraction contrast (from crystal structure and orientation), and more.

Wavelength Dispersive X-ray Fluorescence Spectroscopy
Wavelength Dispersive X-ray Fluorescence Spectroscopy (WDXRF)
In Chemical Composition
Base Price: $400 per Hour

Wavelength dispersive x-ray fluorescence spectroscopy (WDXRF) is a non-contact, non-destructive technique used to measure elemental composition, elemental concentration per unit area, and film thickness. Due to its acute element sensitivity, it is particularly useful for identifying trace elements.
