The NatureXAS 3500 X-ray Absorption Fine Structure Spectrometer is a multifunctional XAFS instrument independently developed by LANScientific with years of technical accumulation.
It adopts a proprietary dual-beam optical system based on the Rowland circle geometry and large curved crystal, coupled with a dedicated X-ray monochromator. It enables high-precision XAFS measurement and analysis in standard laboratories without synchrotron radiation. This design improves optical stability and system repeatability, ensuring consistent and reliable data during long-term operation.
The NatureXAS 3500 integrates XAS and XES modes with fast switching, covering applications from static characterization to dynamic in-situ analysis. It accurately reveals chemical valence, bonding properties, and local coordination structures of target elements.
With outstanding performance and high integration, it is ideal for university research, industrial R&D and advanced material exploration. Typical applications include coordination environment analysis of catalytic metal sites, valence evolution of transition metals in LIB cathodes, and component distribution analysis of fuel cell membrane electrode assemblies.
XAFS directly characterizes active sites in catalysts — such as Pt, Pd, or single‑atom Fe/Co — revealing dynamic changes in their coordination, oxidation state, and electronic structure under reaction conditions. Through in‑situ monitoring, it provides direct evidence for designing efficient catalysts and understanding reaction mechanisms. |
XAFS enables in‑situ tracking of key metals (e.g., Mn, Ni, Co, Fe) in electrode materials under real operating conditions, revealing their valence changes, local structure, coordination, and ion migration. This provides atomic‑scale insights for understanding battery degradation, interface reactions, and developing next‑generation high‑performance batteries. |
XAFS accurately determines the local coordination environment, bond length, disorder, and electronic structure of specific elements in materials — such as dopants and active sites — making it especially suitable for characterizing amorphous phases, clusters, interfaces, and low‑dimensional nanomaterials. It provides essential structural insights for understanding the origins of unique optical, electrical, magnetic, and catalytic properties, enabling targeted performance optimization and design. |
Geology & Mineralogy XAFS accurately determines the speciation, oxidation state, and local structure of key elements (e.g., rare‑earths, transition metals) in geological samples. It reveals their partitioning and migration during geological processes, providing atomic‑scale insights for ore genesis studies, geochemical modeling, and mineral resource utilization. |
Life Sciences XAFS selectively resolves the precise coordination geometry, oxidation state, and dynamic changes of metal cofactors (e.g., Fe, Mn, Zn, Cu) in proteins, enzymes, and biomacromolecules—without disrupting their native states. This provides irreplaceable structural insights into the catalytic mechanisms of metalloenzymes, regulation of metal homeostasis, and interactions between metallodrugs and their targets. |
Environmental Science XAFS directly identifies the chemical speciation, oxidation state, and local coordination structure of heavy metal and metalloid contaminants (e.g., As, Cr, Cd, Pb) in soil, water, and atmospheric particulates. By clarifying the adsorption, complexation, and redox mechanisms at environmental interfaces, it provides crucial molecular‑level evidence for accurate risk assessment and the development of effective remediation technologies. |
