Visualization of Chromatographic Separations by NMR Imaging

Abstract
NMR imaging allows in‐situ observation of interactions between eluant and stationary phase in chromatographic columns. This method, referred to as magnetic resonance tomography in medicine, has been little used so far in chemistry. It provides information on the state of the column (e.g., packing quality and density, flow profile) and allows substances to be observed as they pass through the column.
