600 MHz 52 mm NMR Magnet – HTS Cold Probe

This magnet is equipped with an ultra sensitive superconductor-based probe for direct ¹³C detection in solution microsamples. The magnet is located at the Magnet Lab Tallahassee headquarters.

This solution 600 MHz NMR spectrometer is equipped with a unique 1.5 mm ¹H–¹³C all-HTS Cold Probe. With rf coils made of high-temperature superconductor (HTS), the probe offers ultra high mass sensitivity for NMR experiments. The probe was originally developed in collaboration with Arthur Edison and in partnership with Varian Inc/Agilent Technologies. The sensitivity has been further improved with support from the NIH-funded National Resource for Advanced NMR Technology. Please visit Resource webpage for information on HTS probe technology development and its capabilities or to start a collaboration.

A Varian 5-mm HCN Cold Probe, and a 5-mm and 8-mm room-temperature solution probes are also available for use in this instrument.
