Nuclear Magnetic Resonance Spectroscopy (NMR)
NMR is a quantitative technique for analyzing materials to determine the organic chemical components of a sample.
Most nuclear magnetic resonance spectra are obtained on soluble materials or extracts. However, under special circumstances solid materials can also be analyzed. NMR analysis is performed on polymers, copolymers, and additives.
The most commonly used elements analyzed for structural determination of organic polymers and small molecules are proton (1H) and carbon (13C). Other elements can be analyzed as well, such as silicon (29Si) and fluorine (19F).
NMR is a complimentary technique to Fourier Transform Infrared Spectroscopy (FTIR).
We will help you to determine which method is right for your testing needs.
The NMR technique utilizes a powerful magnet, which means the sample cannot contain iron or other magnetic additives.
A 10 to 50 milligram sample is typically sufficient to obtain NMR spectra with excellent signal to noise ratio.
