Overpressured thin-layer chromatography

Journal of Chromatography A, 1986
The properties, apparatus and applications of overpressured thin-layer chromatography (OPTLC) have been reviewed. In the Introduction planar chromatography has been briefly characterized, with particular attention to TLC. The general properties of OPTLC and methods of development of chromatograms in this technique have been then given. The construction

Contour thin-layer chromatography

Journal of Chromatography A, 1968
Abstract Examinations were conducted of the tendency of migrating substances to ascend on thin strips of varying widths, to follow: 1 cm strips at varying angles above the horizontal compared with the vertical and with reversal of angle of solvent flow, varying degrees of curvature in a single narrow arc or in a series of ascending arcs producing ...
