COMMENTS ON VAN DEEMTER PLOT IN HIGH SPEED COUNTERCURRENT CHROMATOGRAPHY [PDF]

Journal of Liquid Chromatography & Related Technologies, 2001
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

Enrichment and Determination of Zinc by High-Speed Countercurrent Chromatography

Analytical Sciences, 2002
The capability of high-speed countercurrent chromatography (HSCCC) has been investigated for enrichment and determination of metal ions at trace levels. Separation of selected divalent metal ions was performed using a small coiled column. A hexane solution of 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (EHPA) was employed as the stationary ...
