The Chemical Fingerprint of Beer from a Single Experiment with Minimum Sample Preparation – A Rapid Quantitive Analysis by 1H NMR Spectroscopy

NMR Spectroscopy is the premier tool utilized by chemists to obtain detailed chemical information on molecular structure and is used extensively in molecular structure verification, chemical purity analysis, and complex mixture analysis. We have developed a quantitative NMR analysis that…

Quantitative 1H NMR Analysis of “Off-the-Shelf” Commercial Kombucha Beverages for Ethanol, Organic Acids and Residual Sugars Analysis

Over the past few years our analytical NMR service has been developing a detailed chemical fingerprint analysis of alcoholic beverages by quantitative 1H NMR (qHNMR). Beyond the typical analyses of beer, wine, port, hard cider, sake and spirits, we have…

Nutritional Supplement and Diesel Fuel Application Development for Benchtop NMR Systems Operating at 42, 60, and 80 MHz – Equivalency with Supercon NMR

Benchtop high-resolution NMR systems are available at a number of field strengths and probe configurations. However beyond the obvious academic instruction market for these instruments very few applications have been demonstrated across all available platforms and thus proving the general…

Solid-State 13C NMR of Drug API and Tablets

We have an excellent solid-state Doty Scientific Supersonic 7mm CP-MAS probe for our Varian UP-200 spectrometer. This is a nice field strength for solid-state 13C analyses as it allows for spectra at higher sensitivity than a 100 MHz but still…

Trans Fats by 13C NMR

The same trans fat analysis can be performed by 13C NMR. The arrows on the stacked plot indicate the regions of the spectrum tat correlate to trans fat carbon chemistry.

Trans Fat Analysis by 300 MHz 1H NMR

This topic has become pertinent again with the interest of FDA in trans-fat content in processed foods - more information here.Back in 2006 we performed a cursory analysis of trans fat reference materials that we purchased from AOCS. We performed…
