X-ray systems – composition and valence state analysis on trace level

X-ray systems

Based on the patented tunable multi-energy and ultra-bright x-ray sources and highly efficient x-ray optics, our partner Sigray has developed several laboratory systems that are nearly as powerful as comparable synchrotron setups. This includes systems for x-ray fluorescence analysis (µXRF), x-ray absorption spectroscopy (XAS), X-ray absorption near edge structure (XANES), and x-ray absorption fine structure (EXAFS).

Quantum Leap drawing

XAS, XANES and EXAFS can provide answers to important questions regarding the chemical state of the sample, like oxidation, bonding symmetry, bonding lengths and coordinative setup. The XAS system Quantum Leap provides a high sample throughput and sub-eV resolution, similar to that of a synchrotron. As such, the system is able to provide answers regarding the functional characterization of critical materials like catalysts, battery and fuel materials, and electronic components. As a non-destructive method, it allows analyses both in vacuum and under ambient conditions. It also enables in-situ experiments like the examination of the valence state of a battery material during charge and discharge cycles. Results gained from the Quantum Leap can be compared with the results gained from synchrotron measurements.
