FT-NMR: Applications to Instrumental Analysis

FT-NMR: Applications to Instrumental Analysis. 1. Quantitative Analysis -- peak area is directly proportional to # of protons -- pure sample calibration is not required -- use an identifiable (non-overlapping) peak to establish area or use internal standard.

  1. FT-NMR: • Applications to Instrumental Analysis

  2. 1. Quantitative Analysis • -- peak area is directly proportional to # of protons • -- pure sample calibration is not required • -- use an identifiable (non-overlapping) peak to establish area or use internal standard

  3. 2. Analysis of Multicomponent Mixtures -- analysis of analgesics 3. Quantitative Organic Functional Groups -- determination of functional groups

  4. 4. Elemental Analysis • -- Quantitative determination of total hydrogens in an organic mixture. • 5. Analysis of C-13, P-31, F-19, and many more • -- ATP, PHF2, others. • 6. 2-D spectra
