J. Liquid Chromatogr. 14, 1511-1517 (1991). Comparison of separations using conventional TLC plates and Empore sheets in reproducibility, retention time, and solvent systems, using dyes and aflatoxins as model samples.

Reproducibility of silica gel 60 precoated plates in TLC and HPTLC. GIT Fachz. Lab. 38, 973-977 (1994). Study of batch-to-batch reproducibility regarding retention behaviour, selectivity, and separation efficiency. The very small standard deviation of the mean values of the chromatographic data shows the robustness of the TLC method.

Chinese J. Chromatogr. (Sepu) 13, 383-386 (1995). The results showed that the chromatographic performance reached the optimum when the plates coated with a slurry which was prepared with a CMC solution of ca. 1.0% (w/v) in water. These plates have an appropriate rigidity. The finding provides a base for home-coating TLC plates in higher quality.

J. Chromatogr. Sci. 36, 499-504 (1998). Modification of perlite by converting its SiO2 content (70-75%) to soluble silicates with Na2CO3. Investigation of parameters such as particle size, specific surface area, pore size and volume, and surface hydroxyl group density of the material. Demonstration of the separations of dyes, amino acids, carboxylic acids, mono- and disaccharides, and halide ions, using the layer of the material mixed with CaSO4 and Na4SiO4.

J. Planar Chromatogr. 14, 208-210 (2001). Separation of dyes, polycyclic hydrocarbons (phenanthrene, benzopyrene, anthracene, fluoranthene, pyrene, triphenylene, azulene, naphthacene, chrysene, perylene) and a vegetable chlorophyll extract on plates prepared from Piresorb A, silica gel, luminophore and liquid glass as binder with benzene, hexane, benzene - hexane 1:4 and ethyl acetate - acetonitrile 3:7. For flow TLC it is necessary to use TLC plates with sorbents different from those used in classical TLC.

Chromatographia 62 (1-2), 91-97 (2005). Silica gel impregnation with polyethylene glycol of different molecular mass (400, 1000, 1540, 4000, and 5500) was investigated for salting-out thin-layer chromatography of 15 mixed aminocarboxylato Co(III) complexes using eight ammonium sulphate solutions as mobile phases. Regularities established earlier for non-impregnated adsorbents are also valid in this work. Polyethylene glycol of high molecular mass increases the hydrophobicity of the adsorbent. Positive linear dependence of RM values and of salting-out efficiency on average polyethylene glycol molecular mass was usually observed. In contrast with non-impregnated silica gel, separation was achieved between complexes with the smallest hydrocarbon groups.

European Chromatography News 2, 18-21 (1988). Description of some of the many recent innovations like advances in TLC plates, sample application, development techniques and instrumentation for detection, quantification and identification. TLC is described as a sensitive instrumentalized quantitative analytical technique.

J. Planar Chromatogr. 16, 461-464 (2003). TLC of 13 dyes (light yellow G, acid red B, disperse deep blue H-GL, disperse scarlet BWFL, disperse orange 2BFL, disperse balas 2GFL, disperse blue BGL, disperse red 3B, disperse yellow 54, disperse turquoise GL, 10GN disperse fluorescent yellow, S-BGL disperse blue, and 2B disperse black) on silica gel (5 x 40 cm; layer thickness approx. 0.5 mm) with a new mode of 'multidimensional relay' development. Multidimensional relay development with the half-way development device transfers unseparated spots to a new TLC plate on the basis of the first separation, then re-develops this new plate.
