J. Planar Chromatogr. 28, 472-475 (2015). HPTLC of 17α-ethinylestradiol (extracted from water samples using a monolithic stir-bar) on RP-18 with methanol - acetonitrile - water 2:2:1. Detection by heating at 110 °C for 10 min followed by dipping into a mixture of sulfuric acid 98 % in water 1:49 for 1 s. After dipping the plate was heated again to 110 °C for 10 min. The hRF value for 17α-ethinylestradiol was 51.

J. Planar Chromatogr. 23, 426-433 (2010). Mobile phases without addition of buffer salts could be successfully used in planar electrochromatography with a new type of RP-18 sintered plate, prepared from a 1:4 mixture of silica gel for TLC and powdered glass which was suspended in a solution of 0.3 % CMC-Na. The sintering step was the same as already described in J. Planar Chromatogr. 19, 313-318 (2006) except for the temperature which was 651 °C. A suitable degree of bonding of C18 was from 0.03 to 0.06, and good end-capping was achieved by placing the bonded sintered plates in a solution of dimethyldichlorosilane in toluene (ratio 1:100 to 1:1000) at room temperature for 20 min.

J. Planar Chromatogr. 29, 108-112 (2016). HPTLC of water-soluble vitamins (B1, B2, B6, C, and B12), amino acids and β-blocker enantiomers (carvedilol, (S)-(−)-propranolol hydrochloride, (±)-propranolol hydrochloride, and (±)-sotalol hydrochloride) on novel core–shell polymers consisting of hyperbranched (poly(ethyleneimine)) core surrounded by oligosaccharide shell (PEI-OS) as a component of the silica gel phase. The influence of the weight of the hyperbranched PEI core (5 and 25 kDa) was investigated. β-blocker enantiomers were separated using acetonitrile - methanol 7:3. PEI-maltose and PEI-lactose were the most effective polymers for the chiral separation of β-blockers.
