A new in situ cell for XAFS investigations

A new in situ cell for X-ray absorption spectroscopic investigations has been designed and tested. In contrast to existing cells, it is able to reach temperatures as high as 1250 K and can record X-ray absorption spectra in transmission and fluorescence modes. Furthermore, the cell is equipped with a new sample-holder system which allows an easy sample changing. All components are commercial and are simple to build. The cell is light and easy to handle, and can be used under reducing or oxidizing conditions which makes it suitable for performing reduction and oxidation investigations as demanded, e.g. in heterogeneous catalysis experiments. The cell was tested on the reduction of haematite.
