High Resolution
The g-value resolution is dependent on the microwave frequency. W-band EPR offers higher g-value resolution, which is beneficial for analyzing anisotropic samples. For disordered samples such as membrane proteins that are challenging to crystallize, W-band EPR provides enhanced orientation selectivity.
High Sensitivity
With the same sample volume, a high cavity-filling factor improves the detection of low-quantity samples. At the same g-value, a higher resonant magnetic field facilitates better spin polarization, resulting in higher sensitivity in low-temperature experiments.

High Frequency and High Field
Ideal for studying fast kinetic processes and for detecting samples with strong zero-field splitting. Enhances electron-nuclear double resonance experiments by improving the detection and resolution of nuclei with low gyromagnetic ratios.
Cryogen-free Superconducting Magnet
The split-pair superconducting magnet is specifically designed for high-frequency EPR. It employs a cryogen-free system to maintain superconducting temperatures without consuming liquid helium, ensuring stable operation and easy maintenance.

EPR in Geoarchaeology
Quaternary dating (ranging from thousands to millions of years) is achieved through EPR analysis of fossils, rocks, corals, quartz, and soils.
EPR in Biological Structure Analysis
Electron-electron double resonance is vital for determining biomolecular structures. Spin-labeling proteins, RNA, etc., and using EPR to measure their interactions yields non-destructive distance data (1.7–8 nm) between labels.
