EPR100 Spectroscopy: Interview with Dr. Haijun Yang, Analysis Center, Tsinghua University, China

CIQTEK EPR200M is an X-band benchtop electron paramagnetic resonance/electron spin resonance (EPR or ESR) spectroscopy. Based on its high sensitivity and stability, it offers an economical, low-maintenance, and user-friendly experience for EPR study and analysis.   *Accessories: Liquid nitrogen variable temperature with cryostat; 4 mm outer diameter sample tube; Goniometer; Light system; Electrolytic cell; Flat cell.

CIQTEK EPR200-Plus is designed for Continuous Wave EPR studies. Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectrometer 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 spectrometer is particularly useful for studying metal complexes or organic radicals so it has important applications in the fields of chemistry, materials, physics, environment, and medicine.   *Accessories: Liquid nitrogen variable temperature with cryostat; Liquid helium variable temperature; Sample tubes; Goniometers;  Electrolytic cell; Irradiation system; Flat cell.

CIQTEK X-band pulse electron paramagnetic resonance (EPR or ESR) spectroscopy EPR100 supports both continuous-wave EPR and pulse EPR functions, satisfying general CW EPR experiments while performing T1 /T2 / ESEEM (electron-spin echo envelope modulation) / HYSCORE (hyperfine sublevel correlation) and other pulsed EPR tests, which can achieve higher spectral resolution and reveal ultra-fine interactions between electrons and nuclei, thus providing users with more information about the structure of matter.   *Optionally equipped with a 4-300 K variable temperature device to enable the detection of paramagnetic substances at ultra-low (high) temperatures.*Accessories: Liquid nitrogen variable temperature with cryostat; Liquid helium variable temperature; 4 mm outer diameter sample tube; Goniometers; Electrolytic cell; Irradiation system; Flat cell.

CIQTEK EPR-W900 is a W-band (94 GHz) high-frequency electron paramagnetic resonance (EPR or ESR) spectrometer compatible with both continuous wave and pulsed EPR test functions. It is paired with a slit-type superconducting magnet with a maximum magnetic field of 6 T and can perform variable temperature experiments from 4-300 K.EPR-W900 has the same software operating platform as the CIQTEK X-band EPR100, providing users with a user-friendly experience.Compared with the traditional X-band EPR technology, high-frequency EPR has many advantages and has important applications in the fields of biology, chemistry, and materials.
