Automation, Benchtop NMR and Industry

Since it was discovered, the typical trend in NMR Spectroscopy has been towards higher field, evidenced by the rapid replacement of permanent magnets with supercons.[1]  Why?  Well, NMR Spectroscopy, of course, is one of the most information rich molecular spectroscopic techniques available, providing information of the type of nuclei, the number of those nuclei and even how they’re connected.  As you move to higher field you can immediately observe two things: 1) it’s easier to extract the aforementioned information because the resolution is better (i.e., more Hz/ppm dispersion) given the more favourable dispersion and 2) the data has inherently higher signal-to-noise ratio.

The lightest metal with a heavyweight demand: Lithium

The lightest metal with a heavyweight demand: Lithium

Before the early 1950’s lithium was an ingredient found in Seven-up®; however, after concerns by the FDA it was removed from this popular beverage. Interestingly, about the same time it was found that lithium had antipsychotic properties, but it was only approved for human consumption in the 1970’s.[1] Despite being such a simple molecule lithium carbonate is still the most effective drug for the treatment of bipolar affective disorder! We don’t hear this side of the lithium history very often. In recent years this element has become very popular and its demand has increased considerably due to its widespread use in batteries for small electronic devices such as smart phones and laptops.[2]
