New X-ray absorption spectrometer instrument in use

Ion exchange research group has been working on a new table-top X-ray absorption spectrometer. The implemenation of the device is on-going and the first spectrum has been measured from cobalt foil. Work continues and measurement of real samples will start in near future.

X-ray absorption techniques are used to study electronic structure of elements revealing information about their local coordination environment and electron structure. These studies are usually done at large synchrotron facilities but also table-top instruments are available. Ion-exchange group has been building our instrument with help of Helsinki X-ray Laboratory at Physics Department of University of Helsinki.
