Mössbauer laboratories

The Mössbauer technique probes the electronic environment of a few, selected nuclides. Fe and Au are well-known examples. In Europe, RID provides the only possibility to do such measurements with Au-198. Also, RID provides sample environment options that are offer unique possibilities to investigate what happens on the chemical level in your process, as enumerated below.

• Six Mössbauer absorption spectrometers which can be used in ⁵⁷Fe, ¹¹⁹Sn, ¹⁶⁹Tm and ¹⁶¹Dy Mössbauer.
• Two Mössbauer emission spectrometers to investigate ⁵⁷Co containing materials.
• One Mössbauer absorption spectrometer in which the source as well as the absorber can be cooled down to T = 4.2 K, for ¹⁹⁷Au, ¹⁹³Ir, ¹⁶⁶Er and ¹⁴¹Pr spectrometry.
• One Mössbauer absorption spectrometer in which the source as well as the absorber can be cooled down to T = 2.3 K and a magnetic field up to 8 T can be applied, for ¹⁹⁷Au and ¹⁵⁵Gd spectrometry.
• Gas-handling systems and reactors for investigation under Fischer-Tropsch synthesis (hydrogenation of CO) and for investigation under H2S atmosphere. Currently available gasses: H₂S, CO, N₂, H₂, Ar, SO₂, NO and O₂.
• Equipment for cryogenic measurements down to T = 0.3 K and vacuum furnaces for measurements up to T = 1000 K
• A combined CXMS/CEMS detector for measuring surface phenomena and/or thick samples.
• A high-pressure in-situ reactor for Mössbauer emission spectroscopy. This reactor is designed for measuring ⁵⁷Co containing Fischer-Tropsch catalystsup to 20 bar (including 10 bar steam) and 723 K! Thus, industrial conditions!
