In situ/in operando

What it tells you: how your sample changes over time

All of the techniques we offer can apply to our in situ cells, which can do gas/liquid under flow or static, with optional heating and biasing. For more information visit our ‘in-situ’ page, which describes the holders the beamline offers. In addition, we can accommodate bespoke holders.

In addition, we have experience assisting previous users in developing and manufacturing custom electrochemistry in operando cells. Currently, there are a few models available at the beamline (see image below), but we are flexible enough to adapt to your sample and instrumental needs. Furthermore, I14 owns two different pieces of equipment for providing different potentials: Ivium OctoStat (https://www.ivium.com/product/octostat200/) and a Bio-potentiostat (https://www.stinstruments.com/electrochemistry/potentiostat-galvanostat-eis/sp-200-potentiostat/). Please  approach a member of the I14 team to discuss the operational details. Miguel Gomez Gonzalez will be pleased to hear from you to discuss electrochmistry experiments.

Things to consider:

Sample preparation – You will need to apply your sample to a specific chip depending on which holder you choose. The size is limited to the space between the chips (approx. 2-8 microns).

Timescale – The timescale of change needs to correspond with our mapping times (e.g. too quick and you will miss it, too slow and you may run out of beamtime).

Testing – A certain amount of offline testing is usually beneficial to make an experiment successful.

Beam related effects – Some reactions can be induced by the X-ray beam
