5: Q-NMR Applications

  • Page ID
  • This section presents summaries of several common Q-NMR applications. Q-NMR is widely used for both purity and impurity analyses. Q-NMR finds extensive use in the food and beverage industry, where it is used to detect adulteration and to follow the progression of processes such as fermentation. A relatively recent application of Q-NMR is in the area of metabonomics, which follows relative changes in the level of metabolites in biofluids like urine or plasma, or in tissue biopsies to shed insight into complex biological processes including the effect of genetic variations, disease progression, drug efficacy and the effect of toxicants.
