CIQTEK EPR Spectroscopy at the 11th National Conference on Environmental Chemistry (NCEC)
August 02, 2022
From July 25-29, the 11th National Conference on Environmental Chemistry (NCEC 2022) was held in Harbin, China. Nearly 5,000 experts in the field of environmental chemistry from Nanjing University, Tsinghua University, Peking University, and other universities and related research institutes gathered to discuss the development of environmental chemistry disciplines, promote academic research cooperation, and accelerate the construction of environmental chemistry disciplines and talent training.
CIQTEK attended this conference and introduced the solutions of electronic paramagnetic resonance (EPR or ESR) spectroscopy in the field of environmental chemistry to the delegates.

With the theme of "Innovative Environmental Science" and the purpose of "Innovation, Participation, Cooperation and Foresight", this year's conference set up 58 sessions and various topics around different fields such as environmental analysis, public health, environmental safety, pollution control, green and low-carbon, including special sessions for major research programs of the Foundation, Young Scholars Forum and Frontier Forum of Environmental Science.
As one of the global crises, environmental pollution is affecting human life and health at all times. Among atmospheric pollutants, water pollutants, and soil pollutants, there is an emerging class of environmentally harmful substances - Environmentally Persistent Free Radicals (EPFRs). EPFRs are ubiquitous in the environment and can induce the generation of reactive oxide species (ROS), which cause cell and body damage and are one of the causes of cancer, and are highly biohazardous. EPR (ESR) technology can detect EPFRs and analyze them quantitatively to find the source of the hazard and solve the underlying problem.

CIQTEK EPR (ESR) spectroscopy
The CIQTEK EPR (ESR) spectroscopy provides a non-destructive analytical method for the direct detection of paramagnetic materials. It can study the composition, structure, and dynamics of magnetic molecules, transition metal ions, rare earth ions, ion clusters, doped materials, defective materials, free radicals, metalloproteins, and other substances containing unpaired electrons, and can provide in situ and non-destructive information on the microscopic scale of electron spins, orbitals, and nuclei. It has a wide range of applications in the fields of physics, chemistry, biology, materials, and industry.

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.
