Variable Field NMR Spectrometer

The National Physical Laboratory [NPL] requirement is for a Variable Field Nuclear Magnetic Resonance (NMR) spectrometer for the measurement of T1, T2, T2*, apparent diffusion coefficient, and proton density fat fraction in the liquid state. The purpose is to enable traceable, high-precision measurements of these measurands, to allow for the development of metrological standards for Magnetic Resonance Imaging (MRI). The ITT is separated into two components; the Instrument, and the Facility. We welcome tenders for either or both. The Instrument should comprise an NMR Spectrometer, with all associated componentry (e.g., the magnet, console, probe(s), temperature control system, shims, and workstation). This should be a fully programmable spectrometer, with the capability to measure the NMR spectra of chosen samples using appropriate pulse sequences and export the resulting data to an appropriate data storage or archival facility. The magnetic field should be variable, with the ability to change the field on a monthly basis. The magnetic field should be able to reach clinically relevant MRI fields (e.g., 1.5, 2.9, 3.0, 5.0, 7.0 T), and have the capability for lower field strengths down to 0.1 T or lower. The spectrometer should be compatible with the existing equivalent facility at NIST Boulder.
