Improve Workflow with Low Field NMR Spectrometers

In 1952 The Nobel Prize was awarded to Felix Bloch and Edward M Purcell for the first demonstration of the NMR 6 years earlier. This breakthrough changed the world of chemistry. The NMR spectrometer became the industry standard.

The evolution of the Nuclear Magnetic Resonance spectroscopy has been rapid. Recently low field NMR spectrometers have remade their way to market. Today, low field NMR spectrometers are the benchtop NMR spectrometer that provide an additional level of NMR workflow to increase accessibility, affordability and automatability of this powerful characterization technique. 

What are Low Field NMR Spectrometers?

Early NMR spectrometers were not available commercially. They were large and complicated and not suitable for routine bench work in the traditional sense. After 1961 they did become available commercially but, due to the nature of the technology, have remained largely in the hands of experts.  The prevalent high-field spectrometers are higher in cost, require much more maintenance and have steric restrictions you do not have to worry about with low field NMR spectrometers.

Low field NMR, is loosely defined as anything under 200 MHz and can include a range of different NMR from low T’s to a field of zero. There are several applications where low-field provides ideal resolution without the hassle that is associated with the high field NMR spectrometers.

Today it is not unusual to have both a traditional high field NMR spectrometer and low field NMR spectrometers working side by side. Low field benchtop spectrometers can excel in QA/QC, RXN monitoring and ease of use. 

Low Field NMR Applications

There is a wide range of low field NMR spectrometer applications. This science has been around for about as long as the NMR spectrometer has been around but there has been a renewed interest in the technology.

A low field NMR has been used in applications ranging from food monitoring to CBD oil verification to tree drought sensitivity and it is used across a wide range of industries. This type of spectrometer is favored by chemists for ease of use and in applications. It is ideal for both the experienced chemist and the novice.

It’s portability makes it the choice in the lab and beyond. It can be connected for online monitoring and detection throughout all the stages of research and monitoring. It is a simple solution for the bench.
