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…

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…
