The use of chromatographic stationary phases or solvent modifiers to modulate diffusion properties in NMR experiments is now well established. Their use can be to improve resolution in the diffusion domain or to provide an insight into analyte-modifier interactions and, hence, the chromatography process. Here, we extend previous work using size-exclusion chromatographic stationary phases to the investigation of polymer mixtures.

- Chromatographic NMR uses stationary phases or solvent additives to enhance the diffusion behavior of analyte molecules, improving the resolution of measurements.
- The paper explores the effects of size exclusion chromatography on the diffusion coefficients of analyte molecules, using polymer standards of varying molecular weights.
- The findings are analyzed with a straightforward explanation of the size exclusion effect, shedding light on how molecular size impacts diffusion.
