Ley Group at Cambridge uses Spinsolve Benchtop NMR as part of their flow chemistry and organic synthesis research

June 22nd, 2017, by

Professor Steven Ley’s laboratories are located in the Department of Chemistry at the University of Cambridge. Their research specialises in flow chemistry and organic synthesis. They are renowned for collaborations with academic and industrial partners. Précising their work, Steve says

“Complex synthesis remains a challenging occupation requiring an exceptional level of experimental skill, extensive knowledge of both mechanistic and molecular reactivity, and a bold, inventive, and creative spirit. It is the combination of these qualities that transforms the synthesis process from one of simple logistics to an art form.”

Euromar workshop – Advances in benchtop NMR – register here

June 8th, 2017, by

We are holding a workshop during Euromar – Advances in benchtop NMR .

You can register for the workshop by clicking here (spaces are limited).

The workshop will be held in Kopernik Room on July 4th, and will run twice, from 13.30-14.30  and again from 14.30-15.30. Limited to 30 participants.

Benchtop NMR systems have become popular analytical lab instruments in the last years. With the recent launch of the Spinsolve Ultra the magnetic field homogeneity has been improved to match a lines shape that is comparable to superconducting magnets, while the brand new Spinsolve 80 pushes the limits in chemical shift spreading and sensitivity for a benchtop system.

During the workshop an overview of applications that can be addressed with benchtop NMR systems will be given and practical demonstrations will be done on a live system.

Spaces are limited so please register now if you are interested in attending by clicking here.

Silicon NMR on Spinsolve – Part 1

June 22nd, 2017, by

Silicon is one of the most widespread elements in the natural world and, as such, this makes it a very interesting and useful element to study using NMR. Over the past few decades, a wide range of silicon-containing compounds have been investigated using both solid- and liquid-state NMR techniques. For example, siloxane polymers, which are extensively used in biomedical and cosmetic applications, have been extensively studied by NMR to understand their structure and individual building blocks. Similarly, the structure of silicates, zeolites and other materials have been studied by silicon NMR. Silicon NMR has been shown to be a powerful tool for the determination of active end groups, cross-linking moieties and polymer sequencing.

The NEW Spinsolve ULTRA – best resolution and lineshape

March 28th, 2017, by

Thrilled to announce the launch of the NEW Spinsolve ULTRA Benchtop NMR system. The Spinsolve ULTRA has the field homogeneity of a superconducting NMR magnet (0.2 Hz / 6 Hz / 12 Hz) in a compact and robust benchtop unit.

The Spinsolve ULTRA brochure can be downloaded here.

When combined with solvent suppression it allows users to resolve compounds dissolved at sub-millimolar concentrations in protonated solvents, such as water. The example below shows how effective the suppression of the very large water signal is. This enables metabolites at concentrations down to a few hundred micromolars to be detected in an 8 minute measurement.

Please contact us to discuss if Spinsolve ULTRA is useful for your application.

13C NMR of Cholesterol on an 80 MHz magnet

June 14th, 2017, by

Cholesterol is an essential molecule found in all animals and is a structural component of animal cell membranes. It is the reason why animal cells are flexible and animals can move, unlike plant cells which have rigid cell walls. Cholesterol is a sterol and the cells in your body synthesize about 1 gram every day.

With recent advances in the performance of benchtop NMR, such as the 80 MHz Spinsolve 80, it is interesting to see the 13C NMR spectra from molecules such as Cholesterol.  With a molecular weight of 386 g/mol and 27 carbon atoms it is a larger molecule than is typical measured on a Carbon-13 capable benchtop NMR spectrometer. Because there are more peaks to resolve, both the sensitivity and resolution of the instrument are tested with this measurement.

The 1D proton-decoupled 13C NMR spectrum of a 400 mM sample of Cholesterol measured by a Spinsolve 80 is shown in the figure below. Because 13C has a lower gyromagnetic ratio than protons, the 13C Larmor frequency is 20 MHz. The region between 20 ppm and 45 ppm has been expanded to show how the carbon peaks are resolved.

Spinsolve 80: Quinine HSQC-ME example

May 30th, 2017, by

One of the advanced features of the Spinsolve 80 is the ability to run a Multiplicity Edited HSQC, also known as HSQC-ME.  This powerful 2D NMR sequence has proton in the horizontal (f2) axis and carbon in the vertical (f1) axis.  The peaks appear where a proton is connected to a carbon atom.  Additional information about “multiplicity” is given by the sign of the peak, just like in a DEPT experiment.  Positive peaks (red) are either CH or CH3, while negative peaks (blue) are from CH2. This additional information really helps with correct peak assignment.

The example below is from an HSQC-ME experiment run on a sample of Quinine and shows all the peaks uniquely resolved and assigned.
