The NatureXAS 2500 is a multi‑function X‑ray absorption fine structure spectrometer independently developed by Lanscientific, integrating years of technical expertise. The optical path employs a Rowland circle and large‑area curved crystal optics, combined with a proprietary X‑ray monochromator design, enabling XAFS measurements and analysis in a conventional laboratory—without synchrotron radiation. It offers XAS, XES, and XRD measurement modes with easy switching between them. The system is primarily used for studying elemental oxidation states, bond covalency, and chemical environments, providing important insights for materials chemistry and electronic structure analysis, revealing the oxidation states and coordination structures of catalytic active sites, and elucidating catalytic reaction mechanisms and pathways.
NatureXAS 2500 makes cutting‑edge, synchrotron‑level XAFS characterization accessible as a daily laboratory tool. It enables researchers to obtain high‑quality XAFS data flexibly in‑house, eliminating dependence on limited beamtime. By lowering the barrier to advanced analysis, it turns detailed studies of local electronic and coordination structures into routine practice—supporting ongoing discovery, accelerating material design, and deepening mechanistic understanding.
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. |
