The NatureXAS 1500 is a high-performance X-ray absorption fine structure (XAFS) spectrometer developed by Lanscientific through years of independent R&D. Based on a Rowland circle optical path with large curved crystals and a dedicated monochromator, it eliminates the reliance on synchrotron radiation, enabling high signal-to-noise and stable XAFS measurements in conventional laboratory environments.
The system integrates both X-ray absorption spectroscopy (XAS) and X-ray emission spectroscopy (XES) modes, supporting rapid switching during experiments. It provides accurate information on elemental chemical states, bonding properties, and local coordination structures, making it particularly suitable for advanced research such as active site characterization in catalytic materials, electronic structure analysis of energy materials, and dynamic investigation of reaction mechanisms.
Featuring an intuitive software interface, users can simply load the sample and start the measurement, completing high-resolution XAFS data acquisition under in situ conditions within minutes. This significantly lowers the barrier to adopting this advanced technology, transforming in‑depth analysis of electronic structures and coordination environments into a routine research tool for daily scientific discovery and technological innovation, thereby delivering reliable data support for material design, mechanism studies, and process optimization.
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. |
