Over the last few years, more and more analytical and industrial laboratories have started employing quantitative nuclear magnetic resonance (qNMR) spectroscopy as a tool for content assignment (due to its superb structural elucidation abilities) and quantification of purity in a sample.

Repellents are used worldwide to protect against insect bites. This blog describes fun facts about mosquitoes, which substances are considered safe to be used in repellents applied to the skin, and look inside a pure repellent sample via 1H NMR. Read more.

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

In the agrochemical industry, quantifying active ingredients containing fluorine can be simplified by using 19F benchtop NMR instead of other nuclides proton. Read more to find out how.

NMR users can deal with spectrum evaluation in the daily work, but how is the spectrum information stored in the time domain (FID)? Read more.

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.

Nuclear Magnetic Resonance spectroscopy is based on the idea that some nuclei can behave as little magnetic bars (I spin number ≠ 0). In the presence of a magnetic field (B0) the nuclear spins feel a small torque for or against the B0 axis, which results in a net magnetization along the B0 direction. Benchtop NMR 1-855-NMREADY (667-3239) toll-free in the US and Canada.

Hello fellow NMR enthusiasts, have you ever wondered what tritium (3H) looks like via NMR? I know I have, and today, I would like to share some data with you. Read noww.

Proton and carbon NMR analyses are routinely used in organic laboratories. In proton, 1H-1H coupling pattern is well exploited, and 1H-13C couplings as referred to as the carbon satellites. However, when acquiring carbon data, proton decoupling is applied most of the time and consequently it is not common to evaluate 1H-13C couplings in routine carbon analysis. This blog discusses the 1H-13C coupling in tert-butanol through 1D and 2D data, highlighting the key info. Read more.

Parabens are widely used preservatives in food, cosmetics, & pharmaceuticals. Due to their presence in consumer products, methods to determine their purity are important. The current methods using HPLC are powerful, but wasteful and inefficient. In this blog post, we showcase the use of benchtop NMR to quantify the purity of 3 different parabens & demonstrate that this approach is quicker & far less expensive than the traditional methods currently used in industry.
