Abstract
Immobilized free radicals were synthesized and used to shorten the spin-lat tice relaxation times of analytes in the hyphenation of supercritical fluid chromatography (SFC) with proton high-field nuclear magnetic resonance spe ctroscopy (NMR). The effect of the immobilized free radicals was studied fo r the first time under online SFC-NMR coupling conditions. With this method it was possible to obtain integratable NMR spectra in on-line continuous-f low SFC-H-1 NMR spectroscopy. Copyright (C) 2000 John Wiley & Sons, Ltd.
