The "XRD powder" is an Aeris Research edition benchtop X-ray diffractometer from Malvern Panalytical. It is meant for phase analysis of powders, is easy to use, and offers the option of making measurements while heating the sample in a N<sub><sub>2</sub></sub> atmosphere. The setup allows X-ray diffraction measurements in Bragg-Brentano mode (i.e., Theta-2Theta measurements where the incident and diffraction arms of the goniometer are coupled). We have a very limited selection of optics for this instrument, so there is little that the user can adjust. | |||
Please contact the equipment responsible if you would like to mount the special sample holder for heating during the measurement. | |||

Malvern Panalytical has a large collection of webinars on XRD. You have to register to view them but the amount of email you receive afterwards is modest, so it's worth it in my opinion (Rebecca, July 2022). | |||
*A nice webinar about sample preparation: [https://www.malvernpanalytical.com/en/learn/events-and-training/webinars/W20200604XRD.html|Better XRD data quality with good sample preparation] | |||
*A [https://www.malvernpanalytical.com/en/learn/events-and-training/webinars/W20210330XRD.html|beginner’s tutorial] which also mentions sample preparation about half-way through and explains very briefly some of the issues that can arise from displaced samples, not having a thick enough sample layer, odd sized sample particles, etc. | |||

If you are going to make measurements in a heated N<sub><sub>2</sub></sub> atmosphere, you will need the Nambicon software to control the heater.
