What is High-Resolution X-Ray Absorption Spectroscopy？

High-Resolution X-Ray Absorption Spectroscopy is an advanced analytical technique. It probes the fine electronic structure, chemical states, and local atomic environments of materials with exceptional detail, enabling research at the atomic scale.

Core Technical Challenge

The primary challenge is achieving an energy resolution better than 1 eV while maintaining a high signal-to-noise ratio. This is crucial for clearly identifying weak spectral features near the absorption edge, which are often masked in standard XAS measurements.

Three Key Challenges & Our Innovative Solutions

1. Challenge: Balancing High Brightness with High Monochromaticity

Problem: Achieving high resolution requires excellent monochromaticity (pure single-energy X-rays), but traditional methods drastically reduce beam intensity, leading to weak signals and long measurement times.

Our Solution: We employ a combination of higher-harmonic rejection mirrors and advanced channel-cut crystal monochromators (e.g., 4-bounce design). This setup delivers the necessary sub-eV resolution while maximizing usable photon flux from modern, high-brightness synchrotron sources.

2. Challenge: Ensuring Detector Stability & Low Noise

Problem: Long measurement times make data vulnerable to detector noise and instrumental drift, which can obscure the subtle spectral details High-Resolution X-Ray Absorption Spectrometer aims to reveal.

Our Solution: Our systems integrate ultra-low-noise silicon drift detector (SDD) arrays with advanced cooling systems. We combine this with real-time internal reference calibration, continuously correcting for any beam drift or fluctuation to ensure outstanding data stability and reproducibility.

3. Challenge: Compatibility with Real-World Sample Environments & Fast Data Collection

Problem: Researchers need to study materials under real operating conditions (high temperature, pressure, reactive gas flow), and they need data quickly to capture dynamic processes.

Our Solution: We offer modular, compact in-situ sample chambers for various environments and optimize the X-ray optical path for efficiency. Coupled with fast-scanning capabilities, our spectrometers can acquire a high-quality, high-resolution spectrum in just minutes, enabling time-resolved studies.
