We designed the High-Field Field-Cycler to integrate with commercial high-field NMR spectrometers, providing researchers with a highly advanced method for measuring relaxation properties. This instrument delivers exceptional sensitivity and high-resolution spectra, and is capable of conducting diverse field-cycling studies. It has become a vital tool in molecular science, allowing researchers to explore molecular interactions and folding mechanisms through photo-CIDNP. The instrument's capabilities are further enhanced by the inclusion of a correlated illumination device.
We have designed two specialized illuminator models designed to seamlessly integrate with commercial high-field NMR spectrometers.
The first model, the high-field illuminator, facilitates sample irradiation within the commercial high-field NMR spectrometer's sweep spot.
The second model expands measurement capabilities from a fixed field to various fields. Our innovation combines field-cycling techniques with sample irradiation, allowing for variable stray fields within an NMR spectrometer. Importantly, this device eliminates the need for lengthy optical-fiber flipping during shuttling, enabling rapid and precise movement of the field-cycling sample between the illumination and acquisition sweep spots. The shuttle-illumination device is an exclusive add-on to the High-Field Field-Cycler (HFFC), enhancing the capabilities of illuminated NMR experiments.
