      Reversed-phase chromatography of amines, phenols, and metal cations on silica layers impregnated with tributyl phosphate, using surfactant-mediated mobile phases
      A. MOHAMMAD*, N. JABEEN (*Anal. Lab., Dept. of Appl. Chem., Zakir Hussain Col. of Eng. and Techn., Aligarh Muslim Univ., Aligarh-202 002, India)

      Acta Chrom. 13, 135-153 (2003). TLC of 17 metal cations (e.g. Cr3+ from Cr6+, Fe3+ from Mn2+ and Cr6+, VO2+ from Mn2+ and Cr6+) and 14 phenol derivatives (e.g. o-cresol from m-cresol, m-aminophenol from o-aminophenol) on silica gel impregnated with 0.001 M tributyl phosphate, with an 0.01 M aqueous micellar solution of N,N,N-cetyltrimethyl ammonium bromide as mobile phase. An aqueous solution (8.3 × 10-6 M) of the non-ionic surfactant, Brij-35 proved suitable for achieving good separations of 16 amines (e.g. p-dimethylaminobenzaldehyde from L-tryptophan, p-dimethylaminobenzaldehyde from indole) on silica layers impregnated with 0.001 M TBP. Visualization of amine or phenol spots by treatment with iodine vapour for 10 min. Metal ions were detected by spraying with the appropriate chromogenic reagent.

      New method for the quantification of dequalinium cations in pharmaceutical samples by absorption and fluorescence diode array thin-layer chromatography
      Katharina HIEGEL, B. SPANGENBERG* (*University of Offenburg, Institute of Process Engineering, Badstrasse 24, 77652 Offenburg, Germany)

      J. Chromatogr. A 1216(25), 5052-5056 (2009). Diode array HPTLC of dequalinium chloride on silica gel with methanol - 7.8 % aqueous ammonium acetate 17:3. The hRf value was 58 for dequalinium chloride. Measurement of pure dequalinium chloride in the wavelength range from 200 to 500 nm showed several by-products. By densitometric scanning of a single track in absorption and fluorescence mode 600 spectra in the range from 200 to 1100 nm were measured within 30 s. Sample preparation for an ointment was done by dissolution in methanol. Quantitative determination by absorbance measurement from 315 to 340 nm, by fluorescence measurement from 355 to 370 nm, and by fluorescence measurement from 445 to 485 nm after derivatization with a solution of sodium tetraphenyl borate HCl in water. The linearity range of absorption and fluorescence measurements was between 10 and 2000 ng/zone. Sugar-containing preparations like liquids or lozenges can be reliably quantified only in fluorescence mode, otherwise further sample preparation is necessary.
