J. Chromatogr. A 771, 251-257 (1997). Validation of quantitative TLC analysis of test dyes using a Datacolor 3890 color analyser. Recording chromatograms in visible region and the results on-plate diffuse reflectance spectra of the spot, its lightness, chromaticity and hue, with amino acids as example. Comparison of the results with those obtained by image analysis and densitometry, showing color analyser having the lowest R.S.D..

Chromatographia 53 (Sup.), S-474 - S-477 (2001). Study of linearity, precision and detection limit for some test dyes to compare the performance of slit with video densitometry. Results show that video densitometry has equivalent precision compared to slit densitometry, however, has a broader linear range and better sensitivity for the compounds studied. Other attributes of video densitometry are highlighted.

J. Planar Chromatogr. 5, 338-342 (1992). Investigation of the performance of a charge-coupled device for detection of sample bands on a thin-layer chromatogram, whereby the CCD camera is mounted on a modular system configured for mass spectrometric analysis of the same TLC plates. Sensitivity of detection under several modes of illumination for model compounds is explored.

J. Planar Chromatogr. 12, 109-113 (1999). Development of an alternative approach to the direct-immersion washing technique to minimize surface contamination further, or to eliminate it. Plates from 4 suppliers were first washed by ascending development with methanol, dried, and then washed by immersion in the same solvent. Surface residues remaining on the plates were visualized by fluoro- and UV densitometry. The improved, two-step ascending development-immersion prewashing technique yielded adsorbent layers that were essentially free from surface contamination, an essential requirement when residues at the ppb level and below are analyzed by this means. Scanning in the fluorescence mode at 366 nm.

J. of Chromatogr. A 1218 (19), 2648-2660 (2011). Review on the kinetic performance of stabilized particle layers, particle membranes, and thin films for TLC. Forced flow and pressurized planar electrochromatography is best suited to overcome the limited performance achieved by capillary flow for stabilized particle layers. For conventional and high performance plates band broadening is dominated by molecular diffusion at low mobile phase velocities typical of capillary flow systems and by mass transfer with a significant contribution from flow anisotropy at higher flow rates typical of forced flow systems. There are few possible changes to the structure of stabilized particle layers that would significantly improve their performance for capillary flow systems while for forced flow a number of avenues for further study. New media for ultra TLC shows possibilities for miniaturized high performance systems but the realization of their true performance requires improvements in instrumentation for sample application and detection.
