Abstract

Evaluating the parameters for continuous-flow-TLC-chambers it is necessary to determine the flow-parameters of the mobile phase. Based upon the classical theory of Cameron and Bell and Washburn two types of mathematical treatment for solvent-flow problems in TLC are discussed and verified experimentally. The so-called integral method computation gives a more precise result of the flow-constants, whereas the differential method shown as a graph immediately indicates changes in the solvent-flow.
