"When choosing the brand and model of EPR spectrometer, we conducted a six-month measurement sample comparison and found that the effect and service experience of CIQTEK EPR measurement was the best. After an in-depth study, we found that CIQTEK EPR spectroscopy is comparable to imported brands in many key performance indicators, and some of them are even better than others, which can meet our needs in large scientific instruments. At the same time, the rich industry application solutions and perfect after-sales service of CIQTEK also impressed us." Zhou Xiaoyuan, director of Chongqing University Analysis and Testing Center.
CIQTEK EPR (ESR) Spectroscopy
Originating from the Key Laboratory of Microscopic Magnetic Resonance of the Chinese Academy of Sciences at the University of Science and Technology of China, CIQTEK has been deeply engaged in the field of high-end scientific instruments such as electronic paramagnetic resonance (EPR) spectroscopy for more than ten years, and has now launched a comprehensive X-band series for commercial use, and has successfully advanced to W-band high-frequency EPR (ESR) spectroscopy.
EPR (ESR) spectroscopy is a method to study the structure, dynamics, and spatial distribution of unpaired electronics. It can provide in-situ and non-destructive information on electron spins, orbitals, and nuclei at the microscopic scale. They are particularly useful for studying metal complexes or free radicals.

The CIQTEK EPR200-Plus is a floor-standing EPR spectrometer with enhanced sensitivity for robust continuous wave (CW) EPR measurements. The model can be customized with three different sizes of electromagnets. An upgraded version, CIQTEK EPR300, is another floor-standing CW EPR spectroscopy with higher sensitivity and optional Q-band extension. >> EPR200-Plus Accessories: Dual Mode Resonator, High-temperature System, Liquid Nitrogen Variable Temperature With Cryostat, Liquid helium Variable Temperature, Liquid Helium-free Dry Cryogenic System, Time-resolved EPR System, Goniometers, Irradiation system, Flat cell. Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a powerful analytical method to study the structure, dynamics, and spatial distribution of unpaired electronics in paramagnetic substances. It can provide in-situ and non-destructive information on electron spins, orbitals, and nuclei at the microscopic scale. EPR spectroscopy is particularly useful for studying metal complexes or free radicals so it has important applications in the fields of chemistry, materials, physics, environment, etc.
CIQTEK X-band pulse electron paramagnetic resonance (EPR or ESR) spectroscopy 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 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 experimental modes. When paired with a variable temperature system, it enables the detection of paramagnetic substances at ultralow temperatures. Pulsed EPR 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.
W-band (94 GHz) electron paramagnetic resonance (EPR) spectroscopy High-frequency EPR technology offers numerous advantages, such as high g-value resolution and minimal sample volume. It is also highly applicable in biology, chemistry, and materials science. CIQTEK EPR-W900 supports both continuous-wave and pulsed EPR measurement 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 cryostat system, stabilizes the temperature in the superconducting region without consuming liquid helium, ensuring stable operation and easy maintenance. The software platform is the same as the CIQTEK X-band pulsed spectrometer, making it simple and user-friendly.
