In normal TLC practice, migration of the mobile phase through the layer is controlled by capillary forces. Under these conditions the velocity at which the solvent front moves is a function of the distance of the front from the solvent entry position, and this velocity declines as the distance...
An equation, derived in terms of the thermodynamic formulation of TLC with mixed mobile phase, has been discussed. The parameters of this equation, describing solute-solvent interactions in the mobile phase and phase-exchange equilibrium between molecules of both solvents, are determined by using its...
Mobile Phase Optimization in Thin Layer Chromatography (TLC) This review presents the strategies for mobile phase optimization that either have been developed for or have been applied to planar chromatography. In thi... C Cimpoiu,T Hodisan - 《Reviews in Analytical Chemistry》 被引量: 11发表: ...
For automotive electronics, industrial control and other wide temperature, high reliability requirements of the industrial scale application market;Strict production process, comprehensively improve product quality and reliability;High reliability, stable operation in harsh environment. ...
Moreover, we have demonstrated its practical usefulness for predicting solute retention in several different chromatographic modes (i.e. in TLC, normal-phase and reversed-phase HPLC ) employing binary mobile phases. In this paper we give an ultimate check to the physicochemical correctness of our ...
Use of a water-in-oil microemulsion as mobile phase in complexation TLC of amino acids on silica layers impregnated with metal cations A water-in-oil microemulsion has been used for the first time as a mobile phase in thin-layer chromatography of amino acids. A new TLC system comprising si...
What would happen if the level of the mobile phase is higher than the level of the samples on the TLC plates?TLC:TLC is expanded as thin layer chromatography. It has a well known importance in the forensic studies. Here, it is used for determinin...
In the present paper the TLC application of the "PRISMA" model - which was recently developed for mobile phase optimization in normal and reversed-phase HPLC - is described. The performance of the optimization design is demonstrated with the separation of mixtures of naturally occurring compounds in...
Determination of optimal composition of a mixed mobile phase used in separation of different substances by adsorption TLC methods is performed usually by the experimental trial and error method. In this paper we have presented and discussed equations permitting to determine the relationships between RM ...
