COMMENTS ON VAN DEEMTER PLOT IN HIGH SPEED COUNTERCURRENT CHROMATOGRAPHY [PDF]
An inaccuracy in the computation of the linear mobile phase velocity rendered the whole content of a recently published article, Q.Z. Du, P.D. Wu, Y, Ito, J. Liq. Chromatogr. & Rel. Technol., 23(19), 2929 (2000), erroneous. Since the stationary phase volume was given, the correct mobile phase velocity values were computed and the new values for the Van
