Hard Pulse Sequences Research Articles

Continuous-flow nuclear magnetic resonance

The effect of the volume of the detector flow cell upon peak broadening in high-performance liquid chromatography with nuclear magnetic resonance detection has been monitored using a modified fluorescence detector. The results of solvent-resonance suppression using 1331 hard pulse sequences are described. The possibility of obtaining 13C distortionless enhancement by polarization transfer spectra in the flow system is demonstrated.
