On October 31, Guoyi Quantum Technology (Hefei) Co., Ltd. introduced the CryoHe series of nuclear magnetic resonance (NMR) ultra-low temperature probes and the CAN-S series of high-field solid-state NMR spectrometers at the Second Conference on Analytical Science and Instruments. The CryoHe series maintains the core radio frequency coil at approximately 20K, achieving detection sensitivity more than three times that of room-temperature probes. Both products are now capable of mass production and delivery.
