The Center for X-ray spectroscopy provides X-ray absorption spectroscopy services, with the major share being X-ray Absorption Near Edge Structure (XANES) and in some cases extended x-ray absorption fine structure (EXAFS) experiments. The service includes consultation about possibilities of how to use the technique, sample preparation (if required), doing the actual experiment, and preliminary processing of the data. Additional data-analysis services is also offered on request, as well as data modelling when applicable using state of the art codes like FEFF and FDMNES.
The Center for X-ray Spectroscopy is a research infrastructure providing x-ray light for cutting-edge science for both academic and industrial user communities. The Center operates 3 beamlines (X-ray spectrometers).
Clients can use the facilities in person on our site in Helsinki or opt for one of the “hands-free” mail-in services covering many of the X-ray techniques available. Samples can be sent conveniently attached to our standard sample holder - a 3D printed wheel that can hold up to 16 samples. Complementing our x-ray spectroscopy instruments, we are a part of the wider ecosystem of materials characterisation facilities at the Kumpula campus of the University of Helsinki.
