Precise magnet design and fabrication techniques insure a magnet with exceptional NMR performance. Combining Cryomagnetics highly qualified engineering staff with skilled production personnel provides a NMR system without compromise. Due to the nature of NMR spectroscopy research, the magnet must have a large homogeneous high field region with extremely low field drift. A typical 400 MHz NMR system with a 4.00 inch room temperature bore will have a homogeneous field region of 0.1 ppm over a 20 mm diameter by 20 mm long volume. The magnetic field drift specification of the magnet is less than 0.01 ppm per hour.
All NMR magnets are fully tested using state of the art NMR probes and measurement devices at the factory. Customers can be assured of receiving a NMR system that will give quench-free service and meet all specifications. For NMR systems with 1 ppm homogeneity or better, on-site shimming will be necessary. If desired, a highly trained Cryomagnetics’ technician will shim the magnet on-site to null out gradients and off-axis inhomogeneities. While on-site, the technician will instruct the users on how to operate and maintain the system.
