TLCmicellar mobile phasesd-Elements13-diketonatesThe posibility of using a sodium dodecylsulfate (SDS) micelar mobile phase (MMP) to separate Cu (II), Ni (II), Co (III), and Fe (III) ions and their chelates with benzoylacetone and dibenzoylmethane has been examined. Separations were ...
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...

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...
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...
Use of a database of plots of pesticide retention (R F) against mobile-phase composition.Part II. TLC as a pilot technique for transferring retention data to HPLC, and use of the data for preliminary fractionation of a mixture of pesticides by micropreparative column chromatography T. Tuzimski...
Direct resolution of the enantiomers of the racemic drugs ketamine and lisinopril has been achieved by TLC. Enantiomerically pure tartaric acid and mandelic acid were used as chiral impregnating reagents and as mobile phase additives. When (−)-mandelic acid was used as chiral impregnating reagent ...
