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.

Chromatographia 71 (9-10), 907-911 (2010). Description of four-stage TLC, a new version of multidimensional (multi-stage) planar chromatography. In the first stage a multicomponent mixture is fractionated into three groups of chromatographic zones (fractions) by TLC where the adsorbent is deposited on an aluminum foil. In the second stage, the TLC plate is dried and cut by scissors into three narrow strips containing the separated fractions. In the next stages the isolated fractions on each of these strips (“daughter” plates) are separated into individual components with an appropriate mobile phase and by using a solvent flow perpendicular to the flow of the mobile phase. The practical application of the method is shown using as an example the separation of a mixture of dyes. The method can be expanded for separation of mixtures containing four or more fractions. This four-dimensional version of multidimensional TLC was carried out on plates with both open (conventional) and closed adsorbent layers.

Chinese J. Sci. & Technol. Review 17, 220-221 (2013). Zhihe Piba Keli pill is a TCM compound for the treatment of cough. For quality control, microemulsion TLC of Stemona sessilifolia (Miq.) Miq., Morus alba L. and Cynanchum glaucescens (Decne.) Hand.-Mazz on polyamide thin-films with (SDS - n-butanol – n-heptane 2.7:6.3:1.0) – formic acid 9:1, detection at UV 366 nm. Demonstration by applying to real life samples indicated that the procedure was suited for quality control.
