Stream the Webinar: Thinking Outside the (Benchtop) Box – High-Field NMR Techniques on Benchtop Instruments

Did you miss our recent webinar ? No problem, just click the red button below to stream a replay of the webinar held on 27th October 2016: Thinking Outside the (Benchtop) Box – High-Field NMR Techniques on Benchtop Instruments

 




Stream the Webinar Recording



 

In this webinar you will learn about:

  • High-field techniques that are now possible on benchtop instruments.
  • Applications and problems solved by advancements in benchtop NMR spectroscopy.
  • The size, ease-of-use, and economic advantages of benchtop instruments over high-field machines.

In recent years benchtop NMR spectrometers have become an increasingly viable alternative to high-field systems. Many demanding resolution and sensitivity requirements can now be met with modern methods and instruments. In this webinar we illustrate how a number of well-established and modern high-field NMR techniques, such as 2D, non-uniform sampling (NUS), and pure shift experiments, can be implemented on a benchtop NMR system to solve problems and applications previously considered beyond reach.

Quantitative benchtop NMR

September 12th, 2016, by

Quantification using any analytical method requires calibrating an instrumental response with a known reference, and then calculating the concentration of an unknown sample from the measured instrument response. One advantage of NMR compared to other analytical methods is that the signal response is linear, resulting the NMR signal intensity being proportional to the number of nuclei.

Sample concentrations and purities can be easily measured from known peaks once the proportionality constant is calibrated using a reference of known concentration and purity. Such measurement methods are known as quantitative NMR, or qNMR for short.

Karel de Grote University College in Antwerp uses Spinsolve for research and teaching

November 1st, 2016, by

Dr Jeroen Geuens is a member of the Centre of Expertise on Sustainable Chemistry (CESC) based in Antwerp at the Karel de Grote University College. The Centre specialises in research and services related to chemical and production processes together with offering professional degree courses.

Before discovering the Spinsolve benchtop NMR from Magritek they could only get access to NMR measurements by taking their samples to the University of Antwerp. The Spinsolve is now used continuously for both teaching and research in the CESC. Dr Geuens takes up the story.

Benchtop qNMR evaluation

September 18th, 2016, by

In an earlier post on qNMR we described how benchtop NMR can be used to quantify the concentration of a sample or measure its purity. When such quantitative methods are validated, there are standard requirements for accuracy, precision, range, and linearity over that range that need to be met.

For example, the United States Pharmacopeia (USP) specifies the general requirements for a Category I NMR method when measuring a drug substance (there are other specifications for finished products and impurities). These specifications are listed in the table at the end of this post and are compared to the measured Spinsolve performance.

We have validated the Spinsolve benchtop qNMR performance by measuring the purity of one reference standard, methylsulfonylmethane (MSM), with another, maleic acid. Maleic acid is a common reference standard for qNMR, so this was used as the reference to measure the known purity of MSM (specified 99.5% pure). A spectrum of the mixture in D2O is shown in Figure 1.
