In several research fields, only a few milligrams of product are available at the end of the synthesis process. To verify the synthetized structures, heteronuclear multidimensional NMR experiments, like HSQCs or HMBCs, are required. Sensitivity is typically a limiting factor to run these methods in a reasonable measurement time. In this blog post, we investigate …
A chemist´s dream to have a fast and reliable analytical tool that does not require tedious sample preparation and is available within the lab for reaction analysis might have come true with the implementation of efficient solvent suppression methods on mobile benchtop NMR spectrometers. As these instruments use compact permanent magnets, they do not require …
In this blog post, we explore the performance of the Spinsolve Benchtop NMR spectrometers for the identification of phosphine ligands by 31P NMR. Moreover, we demonstrate that the sensitivity of the Spinsolve spectrometers is high enough to monitor the oxidation reaction of these ligands in real time. Phosphines and related phosphorus-containing compounds have been extensively …

Thanksgiving is just around the corner in the US, with the anticipated meal and the nap that follows. There have been several debates from where the sleepiness comes from after the Thanksgiving feast. Is it the copious amount of food, the warm-and-fuzzy feeling from being around families and friends, or the star-of-the-dinner-show turkey? There is …
Typically, NMR samples are dissolved in deuterated solvents to avoid the overlapping of the large solvent peaks with the signal of the analytes. However, if samples need to be analyzed while they are being synthesized or if the components of a liquid formulation need to be quantified the use of deuterated solvents is not an …
