J. Planar Chromatogr. 15, 320-323 (2002). Description of planar electrochromatography in the RP mode in a commercially available development chamber, which requires only small modification for this purpose, resulting in good separation quality and good reproducibility. Only short migration distances < 4.0 cm were obtained under the conditions used. TLC of 17a-acetoxyprogesterone, 2'-acetonaphthone, benzanilide, o-nitroaniline, 3,4-dimethoxybenzoic acid, and p-hydroxybenzoic acid on RP-18 with 55% aqueous acetonitrile containing 25 mM acetate buffer pH 4.5. The potential was 1000 V, applied for 10.0 min. Quantitation by densitometry at 254 nm.

J. Planar Chromatogr. 17, 476-479 (2004). Compared with traditional linear thin-layer chromatography, circular TLC is known to have three advantages: substantially better resolution, lower limits of detection (because of the concentration of the zones), and lower solvent consumption. The results obtained indicate that use of circular electrosmotic TLC (EO-TLC) made the chromatographic process both faster and more efficient. Traditional circular TLC and circular electroosmotic TLC of dyes (rhodamin 6G, brilliant green, sudan III, crystal violet) with DMSO.

J. Chromatogr. A 1164 (1-2), 298-305 (2007). TLC using staining reagents is fast, versatile and sometimes the only viable method method for analyzing organic compounds without chromophores. Investigation of quantitative TLC using staining reagents in combination with modern image analysis software showed that it is possible to get reliable measurements, suitable for high-throughput screening or physical organic investigations. Illustration of the range of detection and the errors for the different parts of the process, which are largely due to the staining process but can be diminished by measuring ratios of compounds.

J. Planar Chromatogr. 26, 26-30 (2013). Four new spray reagents for the detection of amino acids were introduced: (1) 0.25 % solution of benzoic acid in ethanol, (2) 0.1 % solution of p-fluorobenzoic acid in ethanol, (3) 0.1% solution of p-chlorobenzoic acid in ethanol and (4) 0.05 % solution of p-iodobenzoic acid in ethanol. Depending on the different amino acids tested the LOD on silica gel was in the range of 0.1-1.0 µg for all four reagents. For example for cysteine the LOD was 0.1 µg with reagents (1), (3), and (4), and 0.2 µg with reagent (2).

Detection by spraying with a solution of 2mM luminol, 6 mM H2O2 and 0.744 U/mL peroxidase in a 0.094 M tris-HCl buffer (pH 8.5). Determination by densitometry with a single optical fibre that collected the emission signal to a spectrometer. Detection limit 38 ng and 14 ng respectively.
