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. | The "XRD powder" is an Aeris Research edition benchtop X-ray diffractometer from Malvern Panalytical.

The instrument has a 1D strip detector, which makes data acquisition very efficient, so you can measure your samples relatively quickly. The detector also has a fluorescence suppression option, so you can measure samples containing for instance iron with the copper radiation. | |||
Please contact the equipment responsible if you would like to mount the special sample holder for heating during the measurement. | 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). Some useful webinars include: | *Malvern Panalytical has a large collection of webinars on XRD.
