19F Benchtop NMR Spectroscopy for Rapid Hydroxyl Value Determination in Polymers
When analyzing polymers using nuclear magnetic resonance (NMR) spectroscopy, well-defined end-groups (e.g., methoxy, acrylate, vinyl) are typically desired, as these allow for a direct comparison between these end-groups and the repeating monomeric units. This provides a path for rapid and facile determination of the number of repeating units in a polymer, as well as its number-average molecular weight (Mn). Read more.
What to expect: Chemical Shifts & Coupling Constants in Low-field NMR Spectroscopy
One of the questions that we always get at tradeshows and conferences is how our instrument compares to high-field data. There are significant inherent differences between low-field and high-field instruments, but the most important from a chemistry point of view are sensitivity (S/N) and resonance dispersion (signal separation).

Guide: Preparing a Sample for NMR Analysis – Part II
In this blog, we will examine the techniques for ensuring sample homogeneity and explain regarding how the condition of the NMR tube impacts data quality.
Guide: Preparing a Sample for NMR analysis – Part I
In this blog, we highlight the importance choosing the correct NMR solvent and checking the final volume in the NMR tube.
Analysis of herbicides, insecticides, and fertilizers via 31P benchtop NMR
Quantification of phosphorus-containing species through 31P benchtop NMR analysis. It was evaluated one of the most popular herbicides in the world, Roundup®, and a very common household insecticide, 50% Malathion Concentrate®. Read more.
β-Diketone tautomerization ratio determined via 60 MHz benchtop NMR
Tautomers are constitutional isomers that interconvert into each other by an exchange reaction, most commonly a proton transfer. Such two isomers can for example be a ketone and an enol. Read More.
Elevate Your Chemistry Classroom in 2024: Nanalysis Benchtop NMR for Hands-On Learning
As we kick off the new year, educators gear up for an exciting semester, and what better time to explore Nanalysis benchtop NMR? This powerful hands-on learning tool seamlessly integrates real-world analytical techniques into your chemistry classroom or undergrad lab. Read More.
Spicing Up Your Holidays with NMR
If there is one thing that I could say describes the holiday season best, it would have to be the delicious treats I get to indulge in, such as: gingerbread cookies, pies, peppermint bark, and so many more. Wafting in the aroma of baked goods always gives me butterflies in my stomach and lights up my nuclear magnetic resonance (NMR) mind.

Unsymmetric Carbon Satellites in Fluorine-19 NMR
In the 19F NMR spectrum of DCBTF, we can observe the singlet resonance of the trifluoromethyl fragment at δ = −63.07 ppm. While it might not jump into your eye at first glance, please note that the carbon satellites are not centered at the "main signal", which is what we are used to from 1H NMR spectra. Read more
