Both relaxometry and spectroscopy are valued NMR tools for chemical analysis. Both techniques are useful in revealing information on chemical samples. Spectrometers have extremely homogeneous magnetic fields and can provide structural information about composition and connectivity about a molecule whereas relaxometers are less homogenous and provide time-domain data that give information about the bulk properties of a sample such as viscosity and solid fat content.

Process analytical technology (PAT) is a useful tool for optimizing, analyzing, and controlling chemical processes. PAT helps to improve the manufacturing process overall by preventing manufacturing errors, reducing the risk of variability in chemical processes, and monitoring for byproduct formation. PAT also increases the efficiency of the manufacturing process, reduces environmental impact, improves production safety, and reduces costs.

In this blog post, we show an example for on-line flow reaction monitoring via 19F NMR spectroscopy using the compact benchtop NMR. 1-855-NMREADY (667-3239) toll-free in the US and Canada

In this blog post, I’ll feature work done by Vilela et al. with the NMReady-60 and illustrate how it can be used for on-line reaction monitoring and to optimize reaction conditions for the generation of singlet oxygen using BODIPY photosensitisers.

Electronegativity is a concept that we have to study and understand early in our science or engineering degrees. In chemistry this concept stays with us and we commonly invoke it in order to explain multiple phenomena what we observe or study…and of course, NMR is not the exception!

Because of its cost, olive oil is especially susceptible to fraudulent adulteration. Many cases of adulteration are innocuous and involve someone trying to make more money by passing off cheap, inferior oils as authentic extra virgin olive oil. Other cases may be more lethal where someone with criminal intent contaminates olive oil with toxic chemicals, such as the Toxic Oil Syndrome seen in Spain in 1981. 

NMR spectra visualize the change in the Larmor frequency of each hydrogen atom in the analyte. This change is what we call the chemical shift of the signal which is dependent on electronic effects. Similar molecules show similar NMR spectra and this is another advantage of NMR spectroscopy compared to other analytical methods: Derivatives or in this case new psychological active substances or ‘designer drugs’ can be recognized as a potential illicit compound, which is what we are currently working on with police authorities in Germany.
