J. Liq. Chrom. Rel. Technol. 27, 425-435 (2004). TLC of 9 heterocyclic azophenols (e. g. azo derivatives of 2-amino-1,3,4-oxadiazole and 1,2,4-triazole) on RP-2 in flat sandwich chambers with a mixture of phosphate buffer solution + water (or aqueous solution of ion-pairing reagent dimethyllaurylbenzylammonium bromide, Sterinol) + methanol + acetonitrile, e. g. phosphate buffer - water - methanol - acetonitrile 4:4:12:5. Dimethyllaurylbenzylammonium bromide may be used as a counterion for chromatography of ionizable, but coloured, substances.

J. Agric. Food Chem. 56, 8050-8057 (2008). HPTLC of [2-14C]-cymoxanil in the cultures (medium and mycelium) and in the cell-free extracts of Botrytis cinerea on silica gel with hexane - ethyl acetate - acetic acid 70:30:1. The most polar products were separated on RP-18 (impregnated with a methanolic solution of tetrabutylammonium bromide 70 mM and dried at 80 °C for 5 min) with phosphate buffer (0.01 M, pH 6) – methanol 11:9. Detection by autoradiography. The hRf value of cymoxanil was 35 on silica gel. Different metabolites were detected using both stationary phases.

62nd Indian Pharmaceutical Congress Abstract No. F-266 (2010). TLC of metformin and pioglitazone, extracted with methanol from bulk and pharmaceutical formulation, on prewashed silica gel with toluene – methanol – triethylamine 40:10:1. The hRf values of metformin and pioglitazone were 25 and 50, respectively. Quantitative determination by absorbance measurement at 230 nm. The linearity was in the range of 100-1000 ng/band for metformin and 200-1200 ng/band for pioglitazone: the correlation coefficients (r) were 0.9958 and 0.9992, respectively.
