J. Planar Chromatogr. 19, 386-392 (2006). TLC of 11 new 1,2,4-triazole derivatives on RP-18 with mixtures of methanol and water containing from 20 to 70 % methanol in steps of 10 %. Mobile phases containing different additives were prepared by adding the sodium salts of different anions (sodium hexafluorophosphate, perchlorate, trifluoroacetate, nitrate, chloride, iodide, and dihydrophosphate) to the mobile phase. Addition of iodide anions proved a key factor in obtaining lipophilicity indexes which correlated better with the log PG scale for all solutes investigated.

Acta Chrom. 9, 113-122 (1999). Selective separation of Hg2+ from spiked sea and industrial waste water samples. TLC of some inorganic pollutants on silica gel impregnated with potassium thiocyanate (0.01 -2.0 M) 1:1 mixtures of sodium chloride (0.01 - 1.0 M) and formic acid (0.01 - 1.0 M) as mobile phases. Detection with 5 % potassium ferrocyanide in water (for Fe3+, Cu2+, UO22+, VO2+, and Tl+), 0.05 % dithizone in carbon tetrachloride (for Zn2+, Cd2+, Pb2+, Bi3+, Hg2+, Ag+, and Tl+), 1 % dimethylglyoxime in ethanol (for Ni2+ and Co2+), 0.1 % aluminum (for Al3+) and 0.01 % thorine (for Th4+ and Zr4+). The effect of surfactants, halides and oxyanions on the separation of Hg2+ from UO22+ and Fe3+ was examined. The method was used to identify Hg2+, Pb2+, Cd2+, and Zn2+ in synthetic heavy metal sludge samples.

J. Liq. Chromatogr. & Relat. Technol. 29, 2111-2127 (2006). TLC of phospho-lipids on silica gel with chloroform - methanol - water - formic acid 65:35:2:0.04. Detection by spraying with 2’,7’- dichlorofluorescein and under UV light. Phosphatidylserine and lyso-phosphatidylserine were detected by spraying with ethanolic ninhydrin reagent. TLC as screening method prior to the application to TLC-FID by the Iatroscan Chromarod system.

by high speed countercurrent chromatography (HSCCC). J. Liq. Chromatogr. Relat. Technol. 28, 1717-1724 (2005). TLC of triterpene saponins (goyaglycoside-e, momordicoside L and momordicoside K, and goyaglycoside-a) on silica gel with methyl tert-butyl ether, n-butanol, methanol, water 1:2:1:5 and 1:3:1:5; and chloroform - methanol - water 15:4:1. Detection by spraying with 5 % ethanolic sulfuric acid followed by heating at 110 °C.

J. Liq. Chromatogr. & Relat. Technol. 30, 1669-1676 (2007). HPTLC of 14 new growth stimulators (such as amido esters of ethanolamine and maleic and succinic acid derivatives) on RP-18 with methanol - water mixtures in saturated chambers. Detection under UV light at 254 nm.

Pharmazie 60, 269-272 (2005). TLC of (E)-3-[(4-chlorphenyl)imino]-N-isopropyl-3H-1,2,4-triazol-5-amin on silica gel with heptane - tetrahydrofuran -methanol - water 30:20:2:1. Evaluation under white light.

Pharmazie 61, 474-477 (2006). Analytical and preparative TLC of 3-hydroxyl-y-pyranones (3-O-beta-D-(6’-O-linolenic)glucopyranosyl-y-pyranone and erigeside) on silica gel using chloroform - methanol 8:1 and ethyl acetate - methanol - water 12:2:1. Detection under UV light at 254 nm or by spraying with 5 % sulfuric acid in ethanol followed by heating.

Pharmazie 61, 274-277 (2006). TLC of twelve isatin analogues (derivatives of 3-{[(4,6-dimethylpyrimidin-2-yl)benzenesulfonamido-4’-yl]imino}-5-fluoro-1,3-dihydro-2H-indol-2-one) on silica gel with chloroform - methanol 9:1. Visualization by iodine vapor.
