Optimization and evaluation of packed capillary columns for high-performance liquid chromatography
V.L. McGuffin,Milos Novotný +1 more
TL;DR: Packed capillary columns were systematically optimized for adsorption high-performance liquid chromatography, and their performance was evaluated using conventional plate height vs linear velocity curves and the Knox separation impedance as discussed by the authors.

Kinetic optimization of straight open-tubular liquid chromatography
John H. Knox,Mary T. Gilbert +1 more
TL;DR: In this paper, a theoretical analysis of liquid chromatography in open-tubular columns along the lines of the treatment given by Knox and Saleem for packed columns indicates that for a given pressure drop, plate number, solute and eluent, the optimal diameter of the open tubular column is about one fifth of the diameter of particles in the optimal packed column and the analysis time is about 100 times less.

The exclusion properties of some commercially available silica gels
R.P.W. Scott,P. Kucera +1 more
TL;DR: In this article, the effect of the exclusion properties of silica gel on retention data is considered and a modified retention volume equation that takes into account these exclusion properties is given, tested against retention data determined for three different solutes chromatographed on three silica gels of widely different porosities.
