Abstract:

Diffusion ordered NMR spectroscopy (DOSY), sometimes also known as chromatographic NMR (CNMR), is a powerful tool for analyzing complex mixture. However, it is often difficult to distinguish components having similar molecular properties using only the diffusion characteristics. A practical way to solve this problem is adding some matrices, such as silica gel or polymers into magic angle spinning rotor or NMR tube, as the virtual stationary phase (VSP), to increase the difference in diffusion rate among different components. Matrix aided CNMR has been shown to have improved discriminating capability when analyzing complex mixtures. In this paper, recent progresses in the field of matrixed CNMR were reviewed.

Key words: DOSY, self-diffusion coefficient, matrix, chromatographic NMR
