SMART X2S - Sample Preparation and Submission

The following information is provided primarily for external users who wish to utilize the Otterbein SMART X2S for teaching or undergraduate research.

Steps in the crystal preparation / submission / data collection process

  • make (pure) compound – already part of laboratory (hopefully)
  • grow (single) crystals – straightforward for most samples
  • mount crystal – can be done by student, faculty or DHJ
  • collect X-ray data – automated with X2S
  • solve / refine structure – automated with X2S*
  • generate report – automated with X2S
  • analyze results – the important step!

*Note: just about any sample that diffracts with reasonable quality (no cracks, twinning, minimal disorder) will be able to be processed automatically. This allows faculty to shift the focus from the data processing / structure solution process to the analysis of the results of the experiment.

Sample preparation:

Sample preparation and evaluation will typically take place at individual institutions.

Crystal mounting: three options

  1. Students and/or faculty evaluate sample(s) at home institution and mail sample to Otterbein. DHJ will select and mount one (or more) crystals as needed, or...
  2. Individual faculty member brings sample(s) to Otterbein and (with assistance from DHJ), selects and mounts crystal for data collection, or...
  3. Faculty member brings students to Otterbein and together select and mount one (or more) crystals for data collection.

Data collection:

Data collection times will be scheduled and administered by DHJ using the CyberLab software. Students and faculty can remotely start and observed data collection process.

Structure solution / refinement:

If the solution / refinement is successful, data can be downloaded via the CyberLab software. If corrections or additional work is needed, DHJ will assist and upload the revised data archive to the CyberLab storage node.
