Guideline for Users

 

Sample Submission for single crystal:

  1. You are encouraged to use the microscope in the X-ray Diffraction Laboratory to check the quality of your crystal.

  2. Do not remove the crystals from the mother liquor.

  3. Single crystal samples should be checked by the staff of the X-ray Diffraction Laboratory for appropriate size, shape and quality. Samples approved for analysis should be properly labelled and submitted together with a completed request form that has been duly signed by the respective research supervisors/PI.

  4. Please provide the numbering scheme of your structure clearly in the form.

  5. If you have any additional useful information about your crystals or structure, please write in the form. If you suspect that your crystal could be a known compound, please provide the unit cell of the known compound in the form.

  6. If your sample is unstable and needs to be refrigerated or kept in a dry box, please indicate in the form “Call for Sample” and we will contact you when the diffractometer is available.

  7. The request form can be downloaded by clicking the “Forms” button at the right hand side of the webpage.

  8. You will receive the result files by email when the analysis is completed.

  9. If the analysis cannot be proceeded due to poor crystal quality, not diffracting well X-ray or the crystal is a known compound, you will be notified by email.

  10. Please come to the X-ray Diffraction Laboratory to collect back your sample when you receive the abovementioned email.

  11. For sample submitted by non-NUS chemistry members, please include a completed risk assessment form together with your sample. The risk assessment form can be downloaded by clicking the “Forms” button at the right hand side of the webpage.
