Fluorine-19 is one of the most popular nuclides in NMR, along with 1H, 13C and 31P. It has a relatively large chemical shift window (-300 to 400 ppm), which minimizes signal overlap even at low fields, is 100% naturally abundant, and its sensitivity is nearly as high as proton. Read more.

We are pleased to introduce the most powerful benchtop NMR available……the Nanalysis 100 MHz benchtop NMR!!

We have recurring interest from industrial customers (e.g., pharma, flavour/fragrances) to acquire spectra using only small amounts of analyte in our benchtop NMR instruments – considerably less than our recommended 0.1 M concentration (link).  Why is our recommended concentration so high?  Well, it’s reflective of the consequences of a low-field instrument.  That is, lower-field results in inherently lower sensitivity and accordingly a decrease in observed signal to noise ratio (S/N).
