Key Advantages:
- Only laboratory XAS system with synchrotron-like performance
Resolving power of over 6000 and high-quality EXAFS to k=15 - Fluorescence mode XAS

Achieve Synchrotron-Level Performance
Break free from the bottlenecks of traditional synchrotron access. QuantumLeap™ brings the power of high-resolution X-ray Absorption Spectroscopy (XAS)—previously confined to the synchrotrons—directly to your laboratory. No more lengthy proposal cycles, limited beamline time, or logistical delays, our spectrometers provide high quality data in minutes.
Pharmacology and Biochemistry – XANES and EXAFS of Mn with Adipate Ligand (Mn2Adp2) before (G-Mn-Adp) and after (C-Mn-Adp) heat shock (1 minutes at 240 C). XANES (A&B) shows no oxidation state change. FEFF analysis of EXAFS (C&D) shows there was a redistribution of coordination number of the long and short bonds (short bonds increased while long bonds decreased), but the octahedral geometry and presence of 6 oxygen atoms remained the same, indicating the adipate ligands remained intact

Transmission and Fluorescence XAS Modes
X-ray Absorption Spectroscopy (XAS) reveals critical information about a material’s oxidation state, bonding environment, and the local atomic structure by measuring how X-rays are absorbed near an element’s absorption edge.
QuantumLeap™ supports both transmission and fluorescence modes of XAS:
- Transmission Mode: Measures X-rays that pass directly through a sample. Ideal for bulk materials or high-concentration samples.
- Fluorescence Mode: Detects photons emitted as atoms relax after X-ray excitation. Best for low-concentration elements (<1–5 wt%), thick samples, or samples on thick substrates.
Both modes provide the same elemental and structural insights. However, fluorescence mode is essential for dilute or challenging samples—and this is where QuantumLeap™ excels. Thanks to the patented high-flux source and advanced detection system, QuantumLeap™ delivers reliable results for concentrations as low as 0.2–0.5 wt%.

Energy Range from 4.5 to 25 keV
QuantumLeap is the only advanced lab system that operates at low Bragg angles, allowing full EXAFS acquisition from a single crystal—no stitching or multiple datasets required. In contrast, high Bragg angle systems (55°–85°) need many analyzers to cover the energy range and to maintain resolution, complicating operation. For example, at 85°, 1° of crystal rotation covers just 7 eV at 4.5 keV, making it impractical to scan wide energy ranges without sacrificing resolution or using many crystals. This adds manual steps, slows acquisition, and requires time-consuming data stitching.
QuantumLeap uses a patented line focus x-ray source and achieves XAS acquisition at low Bragg angles, enabled by the use of Johansson x-ray crystals

Patented High Brightness X-ray Source with In-built Calibration Targets
Diamond-Enhanced Cooling: In-house design with target materials in direct thermal contact with diamond for superior heat dissipation, enabling higher power loading and brighter X-ray output.
Customizable Targets: Tailored target materials selected in collaboration with customers to match specific application needs.
Internal Spectral Calibration: First X-ray source to feature built-in calibration targets, enabling:
- More accurate energy calibration via spectral lines rather than absorption foils
- Higher energy resolution
- One-time, fully automated calibration—eliminating time-consuming, manual foil calibration required in other systems
Optimized for Fluorescence XAS: High brightness and small spot size support high-quality fluorescence-mode measurements. Please read more in the White paper.

Photon Counting Detector in Transmission Mode
Patented Transmission XAS Approach: QuantumLeap™ uses a novel photon-counting detector—replacing conventional silicon drift detectors (SDDs)—for unmatched speed and precision.
Ultra-Fast Photon Counting: Detects each photon individually with energy thresholding to eliminate harmonic contamination.
Exceptional Throughput: Achieves up to 100 million counts/sec, over 500x faster than traditional SDDs (limited to ~0.5 million counts/sec).
Optimized for High Flux: Ideal for QuantumLeap’s high-flux transmission XAS measurements.
Versatile Operation: Fluorescence-mode XAS is supported using a conventional SDD, ensuring flexibility across applications.

Software
QuantumLeap™ features an intuitive GUI for acquiring data, with minimal user intervention, including the capability to set up recipe-based scans for point-by-point mapping or multiple samples or multiple scans for operando experiments. Data can be exported as CSV files, which can be easily read into analytical software, including Athena and Artemis.
QuantumLeap™software follows an intuitive workflow in which the element of interest is selected, and suggested settings are loaded. Options such as exposure time and the number of images are then entered. The acquired spectrum is displayed in real time during collection.
