A versatile microprobe for x-ray fluorescence imaging and spectroscopy of biological systems.
X-ray capabilities
X-ray fluorescence (XRF) elemental imaging with:
- Tunable spatial resolution, from ≥50 µm to <1 µm spot size
- Tunable energy from 5-80 keV
- 3D XRF imaging: tomography and confocal modes
X-ray absorption spectroscopy (XAS) oxidation state measurements:
- XRF-directed point measurements
- 2D XAS mapping
X-ray diffraction (XRD) phase identification and crystallinity:
- XRF-directed point measurements
- 2D XRD mapping
Multimodal capabilities
- Simultaneous XRF and XRD mapping
- Registration of XRF with complementary microscopy
Supporting capabilities
- Open sample area for custom environments, e.g. beamline-compatible in-situ growth chamber, rhizobox, or cryostat
- Dedicated sample prep facilities including microtome
- On-site plant growth facility with growth chambers, autoclave, and biosafety cabinet
- Complementary optical, fluorescence, and vibrational spectroscopy imaging
- On-site larger growth chamber for plants during beamtime
