X-ray Scattering Facility
Frequently Asked Questions
Check out some of the FAQs for the X-ray Scattering Facility:
Who can use the facility?
The X-ray Scattering Facility is open to all University of Windsor researchers, including faculty, postdocs and graduate/undergraduate students. External users from other academic institutions or industry partners may also access the facility under specific agreements.
How should I prepare my samples for X-ray diffraction analysis?
Samples should be prepared according to the specific requirements of the technique being used. For powder X-ray diffraction, the sample should be submitted in the form of fine powder to maximize particle statistics.
If the assisted data collection is required, it is the user’s/client’s responsibility to supply the sample in the suitable form. Only minor manipulations will be performed during sample mounting. Sample preparation by the Core Manager (e.g., micronizing, grinding) will be charged per hour ($75/hour).
What types of materials can be analyzed?
Solid crystalline samples in the form of powder, polycrystalline clusters or single crystals.
How much sample is needed for an experiment?
Powder x-ray diffraction services conducted on the Proto AXRD Benchtop and Bruker D8 DISCOVER require at least 50 mg of the crystalline powder. Proto-LPD-HT can operate with as little as 3 mg of the sample. Single-crystal diffraction studies require at least one single crystal of the size not smaller than 0.050 in any dimension. Considering the possibility of twinning, it is better to send a few crystals for screening. In case the crystal is provided in the solvate form, it is advised to leave a little bit of residual solvent in the vial to keep the crystals away from desolvation.
How do I book an instrument?
To book time on an instrument consider using Badger. Badger can be downloaded via the link: http://uwindsor.badgerlms.com/badger/News.html
How far in advance should I book an instrument?
We recommend booking powder x-ray diffraction instruments a minimum of 7 days in advance. If you are requesting the data collection on the Proto AXRD LPD-HT, it makes sense to collect a few samples (from the lab members) to make the most of the allocated timeslot.
The single crystal x-ray diffractometer (Bruker D8 VENTURE) is usually on high demand and so we recommend booking the instrument 7-14 days in advance during peak times.
What data analysis services are available?
The X-ray Scattering Facility provides data processing and analysis support, including basic data reduction and advanced modelling techniques. We can also assist with the software recommendations and training.
Can the facility staff help interpret my results?
You can request a certain type of data analysis from the list of services or book a consultation with a crystallographer. Please refer to our Services / User Fees page for more details.
Is training required to use the instruments?
Yes. All users must complete a training session on the specific instrument they intend to use. This ensures safety and proper handling of the equipment. Please visit Core Resources > Training Requirements for more details.
How do I sign up for training?
Training sessions can be scheduled by contacting the Core Manager via email or a phone call.
Can I consult with the facility staff before starting my project?
Absolutely. We encourage users to consult with the staff at the X-ray Scattering Facility during the planning phase of their projects. This can help optimize experimental design and ensure successful outcomes.
Does the facility archive experimental data?
No. The X-ray Scattering Facility does not archive any experimental data. It is requested that all users save a copy of their raw data to a personal drive as soon as the experiment is completed.
Does the facility provide specialized software for data processing?
All the software for data acquisition and processing in the X-ray Scattering Facility is proprietary and cannot be freely distributed. However, users have access to the software on the computers within the facility.
How long can I leave my sample(s) in the facility after the experiment is done?
All samples are removed from the X-ray Scattering Facility within 24 hours without prior notification.
I booked the instrument, but it is busy by another user. What should I do?
Please notify the user that it is your time to use the instrument. In case of a dispute, please address the issue to the Core Manager.
Data collection was aborted due to instrument malfunction. What should I do?
Write down or print screen the error notification. Report the problem via Badger and contact the Core Manager via email. If the instrument malfunctioned outside business hours, stop using the instrument and please also leave a note on the desk (e.g. “This instrument is out of order”).
I arrived at the facility to use the instrument I booked, but it is shut down. What do I do?
There are many reasons why the instrument may have been shut down, including scheduled service, severe weather (e.g., thunderstorms and gale winds) or an unplanned shut down. Please contact the Core Manager to find out if it is safe to turn the instrument on. If you are not familiar with initialization procedure, do not try to tamper with the equipment and wait for the Core Manager.
There is no liquid nitrogen in the tank. What should I do?
The liquid nitrogen policy requires the previous user to exchange the dewars and ensure that there is enough liquid nitrogen for the next person in line. Please, reach out to the last user and ask them to change the dewars. In case of disputes, please contact the Core Manager.
