J. Chromatogr. 703, 573-612 (1995). A review with 194 references on the multidimensionality in planar chromatography, including unidimensional multiple development and two-dimensional controlled or forced flow of the mobile phase, mobile phase gradients and system automation outlining the theoretical consideration, the method development, instrumentation and application. Discussion of the potential of interfacing column and planar chromatographic methods for complex mixture analysis, component identification and trace analysis.

J. Chromatogr. 698, 107-122 (1995). A review with 132 references on the affino immunoelectrophoresis principles and methodology and its use in the study of the mechanisms regulating protein glycosylation of several serum proteins from humans and animals. Discussion of applications of the techniques in fields of biochemical and clinical interest, such as inflammation, cancer, pregnancy, and foetal development.

J. Planar Chromatogr. 9, 107-112 (1996). Examination of the adsorption properties and separating ability of silica modified by addition of sodium hydrogen carbonate. The retention of the chosen 20 alkaloids was examined by the use of a nonaqueous mobile phase and by optimization of the systems by changing the identity and concentration of the modifier. Detection under 254 or 366 nm or with Dragendorff's reagent. Results obtained in the study were used to determine programs for stepwise and multiple-development gradients suitable for the separation of a complex alkaloid mixture.

J. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 21, 161-164 (1996). A review with 33 references stressing at introduction of TLC procedures. Discussion of the sample preparation and some factors affecting the determination.

Anal. Biochem. 308 (1), 106-111 (2002). TLC of cyclic AMP (cAMP) on silica gel with water - ethanol - NH4HCO3 3:7:0.2 M. This procedure separated [32P]cAMP from other radioactive metabolites of [32P]ATP in up to 19 samples on one sheet (20×10 cm) over 40–60 min at room temperature (21 °C). This simple and rapid isolation method provides a novel and convenient technique for the assay of adenylyl cyclase.

J. Planar Chromatogr. 21, 325-329 (2008). Development and systematization of nontraditional TLC methods, in which the chromatographic process occurs in a closed absorption layer on a standard TLC plate. The advantages and limitations of the methods were assessed and the expediency of their further development and wider use in practical TLC was proved.

J. Chromatogr. A 1217(1), 99-103 (2010). Discussion of the definition of multidimensional (MD) separations, especially some potentially powerful separation techniques such as comprehensive 2D LC (LC × LC), and comprehensive 2D GC (GC × GC). The definitions of MD separations have been extended by some researches beyond their intended scope. This disqualifies comprehensive 2D techniques as LC × LC, GC × GC and 2D TLC from being considered as 2D techniques. In other instances, extended treatment of the definition is used as a basis to justify design-parameters of comprehensive 2D separations despite the fact that these parameters lead to sub-optimal implementations. The review draws attention to the shortcomings in the definition, discusses the weaknesses in the currently used definitions, and proposes to define n-dimensional analysis as one that generates n-dimensional displacement information.

Planta Med. 75, 711-718 (2009). For many decades, planar chromatography has been used for the analysis of plants, in particular today in its most advanced form of HPTLC. The technique is e. g. used for the identification of medicinal plants and dietary supplements, and for the detection of adulteration and quantitative determination of marker substances. Reliable qualitative and quantitative results can be achieved based on suitable instrumentation and adequate methodological concepts. The manageability of the entire planar chromatographic process has improved. Integration of biological detection systems as well as hyphenation to mass spectroscopy has widened the applicability of planar chromatography as an important analytical technique. The introduction is followed by explanation of HPTLC, use of HPTLC in plant analysis, limitations, applications (identification, detection of adulteration and quantitation), and instrumentation (chromatogram development, documentation, detection and evaluation).
