摘要

A novel capillary chromatography system has been developed using an open capillary tube and a water-hydrophilic-hydrophobic organic solvent mixture carrier solution; the system is called tube radial distribution chromatography. In this study, we prepared various types of the carrier solution of the water-ethyl acetate (hydrophobic organic solvent) mixture including dioxane, 1-propanol, ethanol, acetonitrile, or methanol as a hydrophilic organic solvent, and examined their separation performance in the system using a fused-silica capillary tube. A mixture analyte of 1-naphthol and 2,6-naphthalenedisulfonic acid was adopted as a model and injected into the fused-silica capillary tube in the system. The analytes were well separated with the water- 1-propanol-ethyl acetate mixture (volume ratio 2:3:6), the water-ethanol-ethyl acetate mixture (2:2:6), and the water-acetonitrile-ethyl acetate mixture (3:8:4) carrier solutions. 1-Naphthol was first eluted from the capillary tube, followed by 2,6-naphthalenedisulfonic acid. However, the analytes were not separated with the water-dioxane-ethyl acetate mixture (4:11:11) or the water-methanol-ethyl acetate mixture (2:2:9). The data obtained here indicated an extension in preparation of the carrier solution by using several hydrophilic organic solvents and provided insight regarding carrier solvent behavior based on the tube radial distribution in the system.
