Sigray QuantumLeap X-Ray Absorption Spectroscopy (XAS) System
Chemical Specification and Electronic Structure with X-Ray Absorption Spectroscopy
With QuantumLeap, researchers will now be able to identify and quantify the chemical species of elements of interest for applications such as:
- Catalysts: chemical states of oxides, nitrides, and carbides being explored as catalysts
- Batteries/fuel cells/solar cells: oxidation state of transition metals (e.g. in lithium ion batteries) as a function of charge and discharge cycles
- Nanoparticles and nanomaterials: structural analysis, coordination number, disorder, geometry, reactivity
Sigray’s QuantumLeap™ brings the long-awaited power of X-ray absorption spectroscopy (XAS) – a synchrotron technique for determining electronic structure of elements – to individual laboratories. Powerful access to synchrotron-grade XANES within minutes at sub-eV resolution and EXAFS at seconds to minutes.
The patented FAAST™ microfocus x-ray source (Fine Anode Array Source Technology) is based on a complete new x-ray source design. The x-ray target is made out of fine metal microstructures that are encapsulated in a diamond substrate. This complete new design was enabled due to recent developments in semiconductor processing techniques.
- Unprecedented ability to analyse electronic (chemical) state of elements
- First laboratory micro-XANES system, providing spatial resolution down to 10 μm
- XANES mode for oxidation state analysis and bond covalency (down to 0.1 eV)
- EXAFS mode for coordination number, types of donors bound, and interatomic distances (<10 eV)
- FAAST™ microfocus X-ray source with 50x higher brightness than sources used in existing non-synchrotron microXRFs due to innovative X-ray target material design
- X-ray mirror lens unique design collects 10x more fluorescence X-rays versus conventional designs
- More powerful source, high efficiency optics and unique paraboloidal geometry results in >100x sensitivity than existing non-synchrotron microXRFs
