Abstract

It is demonstrated that horizontai sandwich tank with two cover plates can be used to preconcentrate sample solutions. Narrow sharply‐defined starting zones are obtained just outside the smaller cover plate when the series of spots of the sample solution are applied on the thin layer and predeveloped with a volatile solvent. After evaporation of the solvent, the whole area of the TLC‐plate is covered with two plates and developed with a suitable solvent.

Base ratio analysis of small amounts of RNA isolated from human specimens requires a sensitive and reproducible method at the level of 5-10 pg of hydrolyzates. We have found that a modification of the method described by Smith and Markham (1) meets both these requirements. Complete separation in 2.

Several methods for evaluating separation quality in two-dimensional thin layer chromatography are discussed. These include using either the distance between spot centers for the pair of solutes that is the most difficult to separate in a mixture, or the value of a suitable separation function, as c
