Know Your Samples

It is important to characterise the samples for a PDF experiment as comprahensively as possible before the beamtime. The three key properties that are required are;
...
- Are there any peaks at low Q? This may require the beamstop to be moved further from the sample. If you have a peak at Q ≤ 1 Å-1 then your local contact should be made aware before the experiment and given a friendly reminder at the start of your beamtime. Q is defined as;
- Have you simulated the pdf and the scattering data for comparison?
- Do you have .cif files that you can bring with you?
- Which of your samples are likely to be the most strongly scattering? This can be effected by the concentration of highly scattering elements, the crystallinity of the sample and the presence of large crystallites in your powder.
- Is your sample a "good" powder? Are there likely to be larger crystallites that need further grinding to give a good powder average?
- Have you packed as many capillaries as you can at your home institution? We will post empty capillaries to you where necessary. Please refer to the "Know Your Setup" section and discuss with your local contact.

All samples should be labelled with the visit number, date, name of the investigator/group and a suitable description of the material (i.e. the full composition including any support materials/binders) |
