Linear) variant, although it is also known in advance that performance of these rules in the former case is considerably worse than in the latter one. The primary reason that no valid rules for preparative TLC have so far been elaborated is due to a rather limited access to densitometric detection, which is still not commonplace in many thin-layer chromatographic laboratories throughout the world. And the demand for densitometric detection in preparative TLC has one very simple reason. Working in the nonlinear range of the experimental isotherms of adsorption of the analytes and because of the resulting mass overload of the respective sorbents, the chromatographic bands cannot be Gaussian in terms of their concentration profiles (or circular, if the spot application and the traditional visualization methods are considered).
