摘要: Investigates the causes of peak tailing in reversed-phase separations of organic cations using single-molecule spectroscopy. Overall patterns of strong adsorption of DiI at the interface between fused silica and water or acetonitrile.年份: 1999 ...
The colloidal crystal outperformed a commercial, silica monolithic product both in terms of peak asymmetry and in resolving the analytes. This preliminary work shows the promise of this material as a substrate for chromatographic separations.The University of Arizona.Legg, Michael Antonio....
The severe peak tailing did not occur with stainless steel tubing when the phosphate compounds were analyzed with carrier containing phosphoric acid or phosphate buffer. The findings indicate that such ill peak profiles are usually not considerable in conventional HPLC separation because phosphoric acid ...
