      J. Planar Chromatogr. 20, 231-233 (2007). TLC of cadaverine and ornithine on calcium sulfate (and silica gel) with methanol. Detection by spraying with 0.2 % ethanolic solution of ninhydrin and then heating the plates at 110 °C for 15 min. Quantitation by scraping the spot from the plate and measuring the absorbance at 550 nm. The lower limit of detection was found to be 0.75 µg/zone of ornithine.

      Separation of aromatic amines on thin layer plates impregnated with picric acid
      M. AJMAL*, A. MOHAMMAD, S. ANWAR, (*Dept. of Applied Chem., Z.H. College of Eng. and Technology, Aligarh Muslim Univ., Aligarh 202002, India)

      J. Planar Chromatogr. 3, 511-514 (1990). Chromatography of aromatic amines on silica impregnated with picric acid has been performed using cyclohexane - benzene mixtures as eluents. The best results were obtained with cyclohexane - benzene 15 on silica impregnated by development with a solution of 1.0% picric acid in methanol. Mutual separation of carbazole, p-phenylenediamine, and p-toluidine from synthetic mixtures containing variable amounts of the compounds has been realized. The method is rapid, and useful for separation amines at microgram as well as milligram levels.

      J. Planar Chromatogr. 17, 431-434 (2004). HPTLC of six heterocyclic amines (2-amino-9H-pyrido[2,3-b]indole, 2-amino-3-methyl-9H-pyrido[2,3-b]indole, norharmane, harmane, 2-aminodipyrido[1,2-alpha3’,2’-d]imidazole, 2-amino-6-methyldipyrido[1,2-alpha3’,2’-d]imidazole) on silica gel by multiple development with diethylether. The mobile phase was selected by using a practical and systematic four-level optimization scheme based on the solvent classification system according to Snyder and the PRISMA model of Nyiredy et al. Quantitative determination by fluorescence measurement at 366/>400 nm was performed immediately after development.
