Magritek, a leading provider of compact NMR and MRI instruments, announces the launch of the Spinsolve ULTRA Benchtop NMR system.

The Spinsolve ULTRA has the field homogeneity of a superconducting NMR magnet (50% 0.2 Hz) in a compact and robust benchtop unit. When combined with solvent suppression it allows users to resolve compounds dissolved at sub-millimolar concentrations in protonated solvents, such as water. 

Magritek, leading suppliers of high resolution, easy-to-use benchtop NMR spectrometers, is excited to announce the release of the Spinsolve ULTRA. Using Magritek’s patented High Homogeneity Halbach Magnets*, the system delivers ultra-high field homogeneity (50% 0.2 Hz, 0.55% 6 Hz, 0.11% 12 Hz) which, when combined with solvent suppression, permits users to resolve compounds dissolved at sub-millimolar concentrations in mixtures such as beverages, fermentations, waste water, and biological fluids in just 8 minutes. Due to the unique features of the Spinsolve ULTRA, no sample preparation is required for the measurement. 

Spinsolve ULTRA is available with multiple different nuclei to give users the possibilities to have a system configured specifically to their requirements. All Spinsolve ULTRA models measure 1H and 19F nuclei but the multinuclear versions offer a third, optional nuclei that can be ⁷Li, ¹¹B, ¹³C, ¹⁵N, ²⁹Si or ³¹P. Users may also ask for the availability of other nuclei. The unit also includes solvent suppression pulse sequences to strongly reduce the signal of protonated solvents that can be more than three orders of magnitude larger than the signals of interest being measured. Spinsolve ULTRA models are available at a choice of operating frequency: 43 MHz or 60 MHz (for ¹H). Furthermore, top class results are produced with no sample spinning, no requirement for compressed air and no need for reference deconvolution data processing. 

The high homogeneity of the Spinsolve ULTRA is particularly useful for samples where the compounds to be identified and quantified are dissolved in protonated solvents such as water. Among important applications are the following: the quantification of sugars and alcohol in beverages; the identification and quantification of metabolites in urine; the analysis of contaminants in waste water; fermentation processes in bioreactors. In general, the high resolution offered by the Spinsolve ULTRA is of great advantage for monitoring chemical reactions performed in the presence of protonated solvents and for qNMR of samples where important signals overlap. 

Magritek's Spinsolve benchtop NMR spectrometers are supplied worldwide to academics in teaching and research; also to industry for research and reaction monitoring through to quality control use.
