J. Planar Chromatogr. 19, 324-326 (2006). GC-MS investigation of dichloromethane extracts from three different types of RP-18 modified silica gel used as TLC adsorbents. Alkenes and carbonyl compounds (two different aldehydes and one ketone) were identified.

J. of Chromatogr. A 1218 (40), 7203-7210 (2011). Investigation of a new method of modifying the elution behaviours of nanostructured thin film UTLC stationary phases, which provides high sensitivity and rapid separation over short distance. Fabrication of macroporous normal phase silica thin films (approx. 5 µm thick) using glancing angle deposition (GLAD). The stationary phase morphology was modified to tune migration velocity, analyte retention, and overall separation performance by reactive ion etching and a subsequent annealing treatment. This allowed the fabrication of adjacent concentration and separation zones with markedly different elution properties. Still the GLAD UTLC phase with concentration zone behaved consistent with traditional TLC and HPTLC layers with concentration zone. The new stationary phase can focus large volumes of a low concentration dye mixture applied as spots into narrow bands.

Trends Anal. Chem. 81, 110-117 (2016). Review of the application of microfabricated pillar arrays as stationary phase for chromatography, including the use of silicon wafers with high cylindrical pillars, modified with a C-18 reversed-phase coating for TLC plates. Chromatographic efficiency increased three to five times compared with commercial TLC plates.

Chromatographia 20, 99-101 (1985). TLC of food dyes, indigo carmin, cochineal red, acid amaranth I, orange yellow S and tartrazine G on thin MgO layers with mixtures of 15 % sodium citrate and methanol in proportions from 9:1 to 1:9. The best proportion of the developing solvent mixture was 6:2. It permits the full separation of the dye mixture from a 0.3 mL sample solution with concentrations of 1 x 10 to minus 6 mole/liter.
