J. Planar Chromatogr. 6, 463-466 (1993). Thermogravimetry for studying the distribution of different TLC impregnating reagents, such as paraffin oil, n-octanol, a quaternary ammonium compound (tricaprylmethylammonium chloride, TCMA), ethylenediaminetetraacetic acid (EDTA), and boric acid on silica gel layers.

J. Planar Chromatogr. 7, 157-159 (1994). TLC of morphine (as dansyl derivative, 5 - 80 ng) and 7-aminoflunitrazepam (as fluorescamin derivative, 100 pg - 2.5 ng); fluorescence enhancement was performed by dipping the developed plate (no details) in a solution of Triton X-100 in a 1:7 mixture of chloroform and hexane. Pre-chromatographic reactions on the TLC plate using a commercially available sampler.

J. AOAC Int. 78, 1141-1144 (1995). TLC of ivermectin after purification and derivatization with trifluoroacetic anhydride on silica with chloroform - ethyl acetate 3:1. Detection after air-drying and dipping in a tank containing 10% paraffin in n-hexane under UV 366 nm. Ivermectin appears as 2 blue spots, one of which is of much higher intensity than the other. The method allows detection of residues in swine and cattle meat, liver, and fat at levels as low as 5 µg/kg.

Anal. Biochem. 231, 447-449 (1995). Description of a method and device for application of samples onto TLC sheets. Discussion of the advantages of the method. Use of the method for preparative TLC.

J. Planar Chromatogr. 11, 325 - 329 (1998). Description of a new type of quasi-column TLC using narrow planar sorbent layers which can be used for separation both in classical TLC and in forced-flow TLC (FFTLC). Some advantages of polycolumn plates over the traditional variety are shown by use of synthetic dye mixtures, e.g. greater separation efficiency, shorter separation time.

J. Planar Chromatogr. 11, 411-416 (1998). Report of an evaluation of one of the newest chromatographic methods, thin-layer electrochromatography on silica gel and aluminum oxide with a strong homogeneous electric field and the monocomponent organic mobile phases commonly used in adsorption chromatography. TLC of polycyclic aromatic hydrocarbons and quinoline derivatives on silica gel and aluminum. The influence of the electric field on the migration velocity of the mobile phase and the chromatographed substances on the cathode side was most evident for ethyl methyl ketone and ethyl acetate.

J. Chromatogr. A 1170 (1-2), 91-100 (2007). Use of three modes of sample application on the chromatographic plate at present investigations of pressurized planar electrochromatography (PPEC) systems taking into special attention their influence on performance of the separating system: 1) application directly with microsyringe, 2) deposition of sample solution on scrap of adsorbent layer followed by location of this scrap on the chromatographic plate, 3) application with a commercially available aerosol applicator. All three modes were combined with prewetting of the chromatographic plates in order to accomplish equilibration of the stationary phase - mobile phase system. Best results were obtained when the plate was prewetted and when application was performed with commercially available aerosol applicator.

J. Planar Chromatogr. 12, 373-377 (1999). Development and evaluation of a new TLC manual multi-applicator for simultaneous deposition of up to 15 samples, successively on several plates of different sizes. Acepromethazine was used as test analyte, and plates were scanned at 375 nm. The multi-applicator furnished good inter-capillary reproducibility (relative standard deviation smaller or equal 4 %) and quantitatively satisfactory linearity (r = 0.996) and reproducibility (RSD = 4 %). HPTLC of acepromethazine maleate on silica gel with methanol. Quantitation by densitometry at 375 nm in absorbance mode.
