High-resolution Spectroscopy
Benchtop permanent magnet bassed system developed to measure high-resolution 1H NMR spectra from samples contained in standard 5 mm diameter NMR tubes. The large sample volume assures that no sensitivity is sacrificed by reducing the size of the magnet, which is a critical issue in small magnets.
The magnet generates a magnetic field of 1T (~40 MHz for 1H) and has a homogeneity better than 0.04 ppm in standard 5 mm NMR tubes. The sensor is equipped with shim coils up to second order and is activey temperature stabilized.
Technical specifications
Benchtop magnet generating highly homogeneous magnetic fields
Spectrum of ethylacetate measured with 8 scans. The high sensitivity of the seystem makes it possible to resolve the the satellites lines corresponding to the J-coupling between 1H and 13C.
