Possibilities of NMR spectrometry in determining trace components of mixtures

The possibility of using nuclear magnetic resonance (NMR) spectrometry for the determination of trace components in mixtures in the concentration range 1 × 10−5–5 × 10−4 M is shown. The conditions of NMR experiments at which the measurement error attains a minimum are standardized and the precision of NMR spectrometry in determining trace components of mixtures within the analytical range is estimated.
