X-ray spectrometer Empyrean XAS

for nanotechnologyfor research and developmentfor environmental analysis

Product overview
Empyrean XAS integrates X-ray absorption spectroscopy (XAS) into the Empyrean multipurpose X-ray platform, enabling laboratory-based XANES and EXAFS measurements alongside XRD, X-ray scattering and imaging techniques. One platform supports multiple structural perspectives and consistent experimental workflows.

Key capabilities

• Determine long-range crystal structure using diffraction
• Investigate nanoscale organization using scattering techniques
• Capture structural imaging data
• Probe local chemical environments using XAS (XANES and EXAFS)

What XAS reveals

• Identification of oxidation states
• Determination of coordination geometry
• Measurement of interatomic distances
• Investigation of short-range order

Measurement approach and performance
Empyrean XAS performs measurements in a dedicated transmission configuration for stable, reproducible energy scanning and quantitative interpretation. High energy resolution supports detailed XANES analysis (including pre-edge features) and a wide k-range for quantitative EXAFS analysis.

Elemental and energy coverage

• Accessible energy range: 4–20+ keV
• Supports K-edges of mid-Z elements (e.g. Ti, Fe, Ni, Mo)
• Supports L-edges of heavier elements (e.g. Ba, Ce)
• Multi-edge capability: measure multiple absorption edges sequentially within a single experiment

Workflow and software features

• Automated data acquisition
• Scan alignment and normalization
• Detector correction and background subtraction
• Pre-edge and post-edge fitting
• Spectral processing and data curation

Applications

• Energy storage — study oxidation-state changes and local structural evolution during battery charge/discharge; track redox processes and monitor electrode material changes
• Catalysis — investigate active sites, oxidation states and reaction pathways in heterogeneous catalysts; understand structure–performance relationships
• Advanced materials — characterize short-range order, defects and electronic structure; investigate nanoscale effects on mechanical, electronic or optical properties
• Environmental & geological science — analyze trace elements and chemical transformations; study speciation and transformation processes in complex environmental materials
