Bruker D2 Phaser

This bench-top diffractometer is our go-to instrument for any samples that contain elements that normally fluoresce under Cu X-rays. It is simple to learn and produces great data for phase-id measurements on powders or small bulk samples.

About

Location: Jesser Hall room 112

The D2 Phaser bench-top X-ray diffractometer from Bruker was added to the lab in May 2023. It is our best diffractometer for measuring the diffraction of samples that would normally fluoresce under Cu X-rays. It is also great for all techniques in which the omega and 2theta arms move in sync. All samples must fit within our powder samples or our small bulk-sample holders (see below for dimensions).
