In many experiments, it is important to be able to separate a mixture into its chemical components in order to isolate one compound or to assess the purity of the mixture. Thin layer chromatography (TLC) is one of the easiest and most versatile methods of doing this because of its low cost, simplicity, quick development time, high sensitivity, and good

Overpressured thin-layer chromatography
Journal of Chromatography A, 1986The 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

Polytetrafluoroethylene layers for thin-layer chromatography
Journal of Chromatography A, 1969Abstract Polytetrafluoroethylene layers have been evolved whose properties are satisfactory for thin-layer chromatography (TLC). These properties include versatility of composition, rate of drying, uniformity, adherence to a support without binder, wettability, rate of development, and resolution of test-mixture components.

Validation of thin layer and high performance thin layer chromatographic methods
Journal of Chromatography A, 2011Analytical validation is a key requirement to asses and to prove a method's reliability and suitability for an intended use. Planar chromatographic procedures are used in different applications ranging from simple screening tests to sophisticated instrumental quantitative assays of analytes in complex matrices.

Thin-layer countercurrent distribution
Analytical Biochemistry, 1965Abstract An apparatus for countercurrent distribution with aqueous polymer two-phase systems is described. The settling time is reduced by using thin layers of the two phases. An experiment with sulfuric acid shows a good agreement between the experimental and the theoretical countercurrent distribution diagrams. A separation of two microorganisms by

Contour thin-layer chromatography
Journal of Chromatography A, 1968Abstract 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 ...
