The CIQTEK EPR300 Electron Paramagnetic Resonance (EPR) Spectrometer incorporates the latest microwave technology and an ultra-high-performance signal processing unit, significantly enhancing detection sensitivity and signal-to-noise ratio to an unprecedented level. It enables precise detection and analysis of unpaired electron signals even at extremely low spin concentrations, providing a novel approach for exploring microscopic physical and chemical properties of low-concentration substances such as free radicals and metal ions. Additionally, the EPR300 supports easy upgrades from X Band to Q Band, achieving higher g-value resolution, which is advantageous for detecting anisotropic samples. The EPR300 establishes a solid experimental foundation for cutting-edge research in life sciences, materials science, chemistry, and physics, driving scientific discoveries to new milestones.

CIQTEK X-band pulse electron paramagnetic resonance (EPR or ESR) spectrometer EPR100 supports both continuous-wave EPR and pulse EPR functions. In addition to supporting conventional continuous-wave EPR experiments, the EPR100 can also finely control and measure electron spin quantum states using specific pulse sequences. This enables pulse EPR tests such as T1, T2, ESEEM (electron spin echo envelope modulation), HYSCORE (hyperfine sublevel correlation), etc. The EPR100 instrument offers a comprehensive range of optional accessories, such as ENDOR, DEER, TR-EPR, and AWG modules, which fully meet the requirements of all current pulsed EPR experimental modes. When paired with a variable temperature system, it enables the detection of paramagnetic substances at ultralow temperatures. Pulsed EPR spectroscopy provides higher spectral resolution, revealing the hyperfine interactions between electrons and nuclei and delivering more detailed structural information. This capability is irreplaceable and crucial in scientific research areas such as materials science, biomolecular structure analysis, etc.

High-Frequency & High-Field Pulse Electron Paramagnetic Resonance (EPR) at W-Band (94 GHz) High-frequency EPR technology offers numerous advantages, such as high g-value resolution and minimal sample volume. It is highly applicable in biology, chemistry, and materials science. CIQTEK EPR-W900 supports both continuous-wave and pulsed EPR measurement, including ENDOR, and enables variable temperature experiments from 4 to 300 K. It is equipped with a split-pair superconducting magnet, with a maximum magnetic field of up to 6 T. The superconducting magnet, combined with a cryogen‐free cryogenic system, stabilizes the temperature in the superconducting region without consuming liquid helium, ensuring stable operation and easy maintenance. The EPR software platform is the same as the CIQTEK X-band pulsed spectrometer, making it simple and user-friendly.
