NMR is excellent analytical tools for the identification and characterization of biomolecules, small molecules, polymers, etc. Whether you need standard spectra for publication of a newly synthesized small molecule or you need a suite of experiments to determine your compound’s orientation or stereochemistry, the Duke NMR Center has the instrumentation and expertise to help you acquire the information you need. Through non-invasive and non-destructive measurements, NMR obtains comprehensive information of the substances which are useful to a wide range of applications in analytical chemistry, life sciences, material science, petroleum exploration, environmental researches, medicinal chemistry and drug discovery.
The Duke NMR Center has several state of the art equipment to address most research endeavors. With instruments ranging from 400 to 800 MHz, cryogenic probes, 16 and 24 position sample changers, the ability to detect NMR active nuclei between 15N and 31P, 4-nuclei probes, and variable temperature range between 150oC to -150oC we provide a robust NMR center to address your research.
