La "RMN Chromatographique"

Abstract : Apparent diffusion coefficients (ADCs) can be measured by nuclear magnetic resonance (NMR) using pulsed field gradient (PFG). The addition of a chromatographic stationary phase allows decreasing selectively the solutes ADC. The sample spins at the magic angle (MAS) to average at zero the anisotropic interactions due to the sample heterogeneity. This method, that we named Chromatographic NMR, was used to apprehend the interactions near the solid phase. After the presentation of both NMR techniques (PFG and MAS), we described two methods developed to investigate the chromatographic process. In this manuscript, we showed the influence of some parameters on the ADCs measured in presence of a chromatographic stationary phase inside the rotor. These results were compared to the data obtained in HPLC. Finally, the limits and the perspectives of the method were apprehended.
