A Sample Cell for in situ EXAFS Measurements [PDF]

, 1983
A sample cell has been built in our laboratory to carry out EXAFS experiments on supported metal catalysts. The cell has the capability of heating the sample to 800 K in the presence of specific gases or in vacuo and then performing EXAFS measurements in situ over a temperature range of 77 K to 600 K.
