SIGRAY QuantumLeap p-H2000

The QuantumLeap is the first laboratory X-ray absorption spectroscopy (XAS) with synchrotron-like performance to provide critical information on oxidation states, bond lengths and interatomic distances, electron symmetry, and more.

  • Description
Description

Features:

  • Only laboratory XAS system within synchrotron-like performance
    XANES at 0.5 eV and EXAFS within seconds
  • Fluorescence mode XAS
    First laboratory fluorescence XAS, enabling XAS analysis of low concentration samples
  • Energy range from 4.5 keV to 25keV
    Range encompasses transition metal such as titanium and platinum… to lanthanides

Transmission-mode XAS (left) measure how many X-rays are transmitted through the sample, who fluorescence-mode XAS (right) measures the number of fluorescent photons emitted by the sample. Both methods can be used to determine how absorbing the sample is. Fluorescence mode XAS is better for thicker samples and samples of lower concentrations, while transmission mode XAS is better for samples of higher concentrations. QuantumLeap-H2000 provides access to both modes.

QuantumLeap-H2000 uses a unique line focus X-ray source and achieves XAS acquisition at low Bragg angles, enabled by the use of a Johansson X-ray crystal.

Achieving a smooth spectrum for XAS: Mo (blue) has characteristic X-ray lines around 2 to 3 keV and 17.4 keV, while W (green) has characteristic energies in the 7 to 12 keV range. By selecting target materials, characteristic lines can be avoided so that a smooth spectrum of energies is acquired for a full range between 4.5 to 25 keV.

QuantumLeap software follows an intuitive workflow in which the element of interest is selected and suggested settings are loaded. Options such as exposure times and number of images are then input. The acquired spectrum is displayed in real time during collection.

Application

  • Catalysts
  • Batteries and Fuel Cells
  • Nanoparticles and Nanotubes
