proXAS

table-top NEXAFS system

  • first integrated NEXAFS spectroscopy solution

  • no need to apply for beamtime

  • chemical state analysis for geology, biology, materials research

  • synchrotron-quality spectra

proXAS is the first system on the market to offer NEXAFS measurements in a laboratory. Fingerprinting for element analysis is now possible in-house with fast and accurate results.

It combines a highly-reliable laser-based XUV source and a customized spectrometer with an extremely high resolving power of 1900. The energy range 200-1200eV allows for measurements at the K-edge of elements such as C, N, O, Ca, K, Ti.

Customized versions of proXAS are available. For applications at higher energies, see hiXAS. Please contact us to discuss your application.
