A new design for a Mossbauer in situ cell for the studies of catalysts and nanometer-sized particles is described. The cell is very versatile and allows measurements in the temperature range from 5 K to about 800 K with the sample in vacuum or exposed to gases. The cell is designed to be used for Mossbauer studies in large applied magnetic fields. The samples can also be separated from the gas-manifold for long term storage in a controlled enviroment and for studies by other experimental techniques such as magnetic measurements. The application of this system is illustrated by results of measurements on carbon-supported alpha-Fe nanoparticles.
