Standard Experimental Hutch for Efficient XAS, both ex- and in-situ
...
The room temperature chamber can be removed and in its place we can accommodate for user supplied in-situ cells, eg for catalysis, provided the cell fits a space envelope of approx 10 x 10 x 10 cm. An example is shown below (see doi.org/10.1021/acs.energyfuels.1c04072). We use a Newport Kinematic Base (M-BKL-4) as the adapter plate between the stage and in-situ cell.

|---|
The beamline does not have an in-situ cell, users supply this themselves. We can however put new groups in touch with those more experienced with the set-up and groups often cross-pollinate ideas and designs. |

A capillary set up and hot air blower from the Powder Diffraction Beamline is pictured below. Please note that because this resource is shared between beamlines, availability is not guaranteed. This is used for variable temperature experiments up to 700°C (this upper limit may be lower for certain flammable gases such as H2), and/or where samples are maintained under a specific gas atmosphere either as flow-through or under pressure up to a maximum of 20 bar. The beamline delivers gas through 6 mm nylon tubes. Please note that these are rated to 10 bar only. If working at pressures above 10 bar, bring your own steel lines.
🧐Where can I purchase suitable capillaries?
Capillaries can be ordered from e.g. Hilgenberg or Charles Supper, and standard stock items will take at least two weeks to be delivered. For non-standard thicker-walled quartz capillaries, users will need to contact Hilgenberg directly for pricing and availability. Delivery time might be longer.
