Dünnschicht-Chromatographie. InCom Sonderband 1996, 212-224. Summary of basic techniques (unidimensional multiple development, incremental multiple development, gradient multiple development, bivariant multiple development; rechromatography with a mobile phase of constant composition; rechromatography with a mobile phase gradient); possibilities and limitations of the method are also reported.

J. Chromatogr. A 816, 97-105 (1998). Use of adsorption TLC to separate proteins with albumin, transferrin, lactoferrin and lysozyme as the model compounds on DEAE anion exchanger with solution containing sodium phosphate, 0.01 M bicine and sodium chloride, Optimization of the pH values for the separation, giving pH 8.5 as the optimum.

I. Preliminary results. J. Planar Chromatogr. 15, 425-428 (2002). Description of a horizontal chromatographic chamber used to study experimentally the principle of planar dielectrochromatography, in particular the increase of the mobile phase front velocity and the dielectrophoretic force generated at granule level on different ready-to-use plates. TLC of a lipophilic test dye mixture (indophenol blue, Sudan red G, 4-dimethylaminoazobenzene) and of a hydrophilic test dye mixture (Brilliant Black BN, amaranth S 75, fast yellow, chryosine) on silica gel, aluminium oxide, and cellulose with benzene and propanol - water - ethyl acetate 6:3:1.

Chemistry of Plant Protection 12, 181-195 (1995). AMD as a TLC technique, which combines the wide range of polarity gradient elution on silica with a separation power similar to HPLC. Application to parallel analysis of 12 samples for some dozens of pesticides. Limit of quantification is 0.05 µg active ingredient per liter. First step allows screening for active ingredients, second step confirms positive results by gradient separation and comparison of UV spectra of sample and standard. Offline-coupling with MS. Standardization as DIN method 38407-part 11 for determination of pesticides in ground and drinking water.

Bio. Chromatogr. 21(1), 94-100 (2008). The method for detection of tyrosinase inhibiting substances involves spraying of the TLC layer with tyrosinase and l-tyrosine solutions successively. Positive results are detected as white spots against a brownish-purple background. The method is suitable either as a quick screening method for tyrosinase inhibitor detection or as a guiding procedure for an isolation of tyrosinase inhibitors from mixtures or natural product extracts. The technique is sensitive enough for results in the presence of 6 ng/zone glabridin.

J. Planar Chromatogr. 27, 340-345 (2014). TLC and HPTLC studies on the influence of application of external magnetic field during chromatogram development for the separation of multicomponent mixtures of flavonoids and phenolic compounds in plant extracts of Hypericum perforatum L., Salvia officinalis L., Matricaria chamomilla L., Thymus vulgaris L. and Achillea millefolium L. The inductivity of the field used in the experiment was about 0.44 T. The method had the potential to modify peak number, retention and width of the peaks.

J. Planar Chromatogr. 30, 440-452 (2017). For electroseparation experiments in a commercially available, open-air electrophoresis box, thirteen types of separation layers (filtrating paper, office paper, chromatography paper, Japanese paper for aircraft paper models, potato starch on cellulose support, common HPTLC glass plates coated with cellulose, silica gel, RP-18W, and aluminum oxide as well as glass-based nutrient agar layers) were investigated. The best separation was observed for the cellulose pre-coated TLC layer and the starch layer on filtrating paper support. The study revealed substantial differences between the electrophoretic migration of target dyes within cellulose type layers and also in comparison to the remaining stationary phases studied. Combined planar electrophoresis–electrochromatography of methyl red and ponceau R colorants on active thin-layers composed of starch powder on cellulose strips and agar layer on glass-based support connected with electrolyte containers. The resulting dye pattern on active layers was acquired using an office scanner.
