Abstract

The outer phase in tube radial distribution chromatography (TRDC) operated as a stationary phase in chromatographic separation. Chromatographic peak information from model analytes 1-naphthol, 1-naphthalenesulfonic acid, 2,6-naphthalenedisulfonic acid, and 1,3,6-naphthalenetrisulfonic acid was examined using TRDC at various flow rates, using a fused-silica capillary tube (inner diameter, 75 μm; length, 120 cm; effective length, 100 cm) as the separation column and water/acetonitrile/ethyl acetate (3:8:4, v/v/v) as eluent. From the data, the relationships between average linear velocities and values of height equivalent to one theoretical plate of the analytes were investigated, and the separation efficiency by TRDC, comprising an inner phase (mobile phase) and outer phase (stationary phase) in an open-tubular capillary tube, was examined using the van Deemter equation.
