[AI-EPR Q&A] Answers to Address User Concerns

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.
