Nuclear Magnetic Resonance (NMR)
Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and research for determining the content and purity of a sample.
NMR is trusted by government agencies for applications ranging from forensic science and drug discovery to food safety and environmental monitoring.
For food and natural health products, we believe NMR is an excellent analytical method to detect product or ingredient adulteration. As a non-targeted analytical method, it can provide a complete picture of all the compounds in a product - not just one specific predefined target.
Why Nuclear Magnetic Resonance (NMR)?
For authenticity testing, NMR is a powerful fit-for-purpose technology.
Cost Effective and Efficient
Unlike other methods, one NMR test can provide a wealth of information about a sample, answering multiple questions in a single test e.g., species identity, presence of synthetics, presence of unexpected substances (adulterants).
Quantitative Analysis
Unlike some methods, NMR is inherently quantitative. This is crucial for authenticity testing, where precise measurements are necessary to detect even minor deviations in the composition of a sample.
Non-Targeted Analysis
Unlike targeted methods that focus on specific compounds, NMR enables non-targeted analysis that can detect a wide range of compounds simultaneously without prior knowledge of what to look for. This versatility and unbiased approach are vital for authenticity testing, where fraudulent substances might not be known in advance.
Traceability
NMR can often be used to determine the geographic and biological origin of a sample. By comparing the NMR spectra of samples of unknown origin with a database of authentic samples, it is possible to trace the origin of a substance, such as the source of a particular type of olive oil.
