Quantitative nuclear magnetic resonance spectroscopy. Purity determination of organic compounds used for foods and food products. General requirements for 1H NMR internal standard method
1 Scope
This document specifies general requirements and performance criteria for the determination
of purity of organic compounds through the application of solution state proton ( 1 H) quantitative nuclear magnetic resonance (qNMR) spectroscopy using an internal standard
method.
This document is applicable to bioactive compounds in functional foods, natural toxins,
food additives and pesticides.
This document is applicable to the users pursuing metrological traceability of the
measurement results.
