Ion-Exclusion Chromatography for Analyzing Organics in Water

A liquid-chromatography technique has been developed for use in the quantitative analysis of urea (and of other nonvolatile organic compounds typically found with urea) dissolved in water. The technique involves the use of a column that contains an ion- exclusion resin; heretofore, this column has been sold for use in analyzing mono- saccharides and food softeners, but not for analyzing water supplies.
