A large spectrum of nonvolatile trace organics from various water samples has been preconcentrated for the subsequent high-resolution analysis. The separations involve microcolumn liquid chromatography with UV detection at 230 nm and capillary supercritical fluid chromatography with flame ionization detection. Water samples from different sources have shown different degrees of complexity. Recoveries at part-per-billion levels, between 60% and 90%, are obtained for model solutes.
