Benchtop qNMR evaluation

In an earlier post on qNMR we described how benchtop NMR can be used to quantify the concentration of a sample or measure its purity. When such quantitative methods are validated, there are standard requirements for accuracy, precision, range, and linearity over that range that need to be met. For example, the United States Pharmacopeia …

Quantitative benchtop NMR

Quantification using any analytical method requires calibrating an instrumental response with a known reference, and then calculating the concentration of an unknown sample from the measured instrument response. One advantage of NMR compared to other analytical methods is that the signal response is linear, resulting the NMR signal intensity being proportional to the number of …

Gradients in NMR Spectroscopy – Part 6: Mixture Analysis by Diffusion Ordered Spectroscopy (DOSY)

In part 5 we introduced the PGSE experiment to measure self-diffusion coefficients. We saw that if the peak integrals are displayed as a Stejskal-Tanner plot we can immediately identify if there is a single self-diffusion coefficient or not. This works pretty well for neat liquids, or solutions with a single type of molecule, or even …
