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