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. This is due to the increase in regulations being imposed by governments onto the pharmaceutical and environmental sectors. It has been previously demonstrated that qNMR spectroscopy can give results with less than 1% uncertainty and possibly down to 0.1% if the right conditions are met.

How strong was your coffee this morning?

Who doesn’t want to start the day with a warm cup of coffee? Coffee has a stimulating effect on humans because of its caffeine content and for that reason it has become one of the most popular drinks in the world. Some clinical studies actually suggest that small amounts of caffeine everyday might be beneficial for adults. In this blog I am going to highlight an experiment done in collaboration with the Swager group at MIT using an organometallic complex to quantify the caffeine content in regular coffee without sample preparation!
