services: Chemical/Elemental Analysis
With comprehensive chemical and elemental analysis available for materials in bulk, thin film, solution and other forms. We can provide qualitative or quantitative composition and chemical analysis across length scales down to atomic resolution.
RELEVANT TECHNIQUES:
FOURIER TRANSFORM INFRARED SPECTROSCOPY (FTIR)
FTIR is a powerful and widely applicable vibrational spectroscopy technique to study chemical bonding and identify molecular structures. The technique can be applied to liquid, solid or gaseous samples and our facilities are also equipped with FTIR microscopy to analyze small specimens or areas of interest.
Our current range of FTIR tools can be found in our KECK-II Facility.
RAMAN SPECTROSCOPY
aman spectroscopy is a vibrational spectroscopy technique, traditionally used to identify the molecular “fingerprint” to help identify chemical structures. The technique is also widely used in the field of 2D materials and can provide additional information about material properties such as crystal orientation or internal stresses.
Our current range of Raman microscopy tools can be found in our SPID Facility.
ELECTRON MICROANALYSIS
The bevvy of signals produced by the electron-specimen interaction can provide a range of useful information about your sample. X-ray microanalysis techniques such as energy or wavelength dispersive spectrometry (EDS or WDS) are available on many of our systems to provide high spatial resolution elemental analysis. In addition, some of our TEM systems are equipped with electron energy loss spectrometers (EELS) for elemental and chemical analysis. We also have crystal orientation mapping capabilities by electron backscatter diffraction (EBSD).
Our current range of microanalysis instruments can be found in our EPIC-SEM and EPIC-TEM Facilities.
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.

MASS SPECTROMETRY
Mass Spectrometry measures the mass-to-charge ratio of ions from a sample, producing a mass spectrum to identify elemental or molecular species. This technique can be applied for a diverse set of research areas from pharmaceuticals to geology. Our tools can handle a range of samples and provide qualitative or quantitative analysis, with or without chromatographic separation.
Our current range of Mass Spectrometry tools can be found in the IMSERC Facility.
NUCLEAR MAGNETIC RESONANCE (NMR)
NMR allows the determination of molecular structure by analyzing the interaction of nuclear spins in a magnetic field. This enables the identification of unknown substances, analysis of polymers, study of reaction dynamics and diffusion coefficients. Our systems are fitted with auto samplers for automated data acquisition.
Our current range of NMR tools can be found in the IMSERC Facility.
