Analysis of herbicides, insecticides, and fertilizers via 31P benchtop NMR (Copy)
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.
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.
Beyond Structure Elucidation - Introduction to qNMR Part II - Calibrants
In this blog post, I will talk about how to select a suitable calibrant as well as the difference between using an internal and external calibrant. When conducting qNMR experiments, one of the first things that needs to be considered is how the calibrant is employed to quantitate your sample. Read more.
Beyond structural elucidation, introduction to qNMR – Part I
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. Read more.
Do Mosquito Bites Annoy You? Investigating Neat Repellent Using 1H NMR Data
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.
The Wonders of Fluorine-19 NMR Spectroscopy for Pesticide Analysis
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.
Fluorine NMR: Enhancing your NMR toolbox with this ideal NMR handle
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.
Assay of Parabens via Benchtop NMR: An Alternative to HPLC
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.
