Online high-performance size exclusion chromatography-nuclear magnetic resonance for the characterization of dissolved organic matter.

Abstract

The substantial heterogeneity of dissolved organic matter (DOM) inhibits detailed chromatographic analysis with conventional detectors as little structural information can be obtained in the presence of extensive coelution. Here we examine the direct hyphenation of high-performance size exclusion chromatography (HPSEC) with nuclear magnetic resonance (NMR… (More)
