NMR probes are critical components of NMR spectrometers. The samples are hold in the probe and positioned at the center of the magnetic field. The RF coils of the probes are used to emit high-power RF pulses for the excitation of nuclear spins and to detect NMR signals. The probes also incorporate an actively shielded gradient coil of high linearity, to generate pulsed-field gradients, enabling experiments such as automatic shimming, coherence selection, and solvent suppression. Q.One offers a range of high-performance liquid-state room-temperature probes. Conventional broadband probe provides acqusition/decoupling of ¹H/19F and common heteronuclei for small-molecule, expanadble to low-gamma nuclei. We also provide three-channel probe (such as X/F/H) and triple resonance probe (H/C/N) to meet the requirements for advanced applications.
