QuantumLeap - X-Ray absorption spectroscopy system for XAS, XANES und EXAFS

from SIGRAY

Sigray’s QuantumLeap™ brings the long-awaited power of x-ray absorption spectroscopy (XAS), a synchroton technique for determining electronic structure of elements, to individual laboratories. With QuantumLeap, researchers will now be able to identify and quantify the chemical species of elements of interest.

Further information

Three core new approaches enable the QuantumLeap unprecedented performance:

x-ray source featuring an innonvative microstructured x-ray target
proprietary high efficiency x-ray mirror lens
innovative detector geometry.

With QuantumLeap, researchers will now be able to identify and quantify the chemical species of elements of interest. It pairs a cutting-edge multi-energy x-ray source with state-of-the-art capillary optics and switchable analyzer crystals for high energy resolution and fast acquisition times. QuantumLeap provides access to XANES and EXAFS data without the need for a synchrotron:

XANES can be provided at sub-eV energy resolution on the range of minutes to an hour
EXAFS at high throughput in seconds to minutes
Wide energy coverage range for analysis of a broad range of elements
MicroXANES at 100 micron spot size
