Introduction

  • 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.

Elemental range

Range of elements accessible for table-top NEXAFS measurements

The range of elements accessible to proXAS for NEXAFS measurements includes the K-absorption edges of C, N, O, F, as well as the L-edges of K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu.

Even diluted samples with analyte concentrations of only 0.2 wt% can be measured.

Results

NEXAFS sample spectrum goethite hematite

NEXAFS spectrum at the oxygen K-edge of the oxide minerals goethite, hematite, ferrihydrite, and CCa-2 chlorite.


(1) measured with the table-top NEXAFS system, measurement time 5min

(2) NEXAFS spectrum recorded at a synchrotron for comparison


Peak positions deviate by less than 0.06% in energy, underlining the excellent agreement of proXAS measurements with synchrotron data.
