      Merits of quantitative planar chromatography - criteria of an analytical problem that make HPTLC a promising candidate
      D.E. JÄNCHEN, (CAMAG, Sonnenmattstr. 11, CH-4132 Muttenz, Switzerland)

      InCom-Sonderband 109-115 (1997). Indication of suitable criteria to choose planar chromatography for the solution of analytical questions like screening and/or confirmation of positive findings using four examples: 1. Confirmation of absence of carcinogenic amines derived from azo dyes (for screening one-step isocratic development on silica, derivatization by diazotation followed by coupling with N-(1-naphthyl)-ethylenediammonium dichloride and evaluation by visual comparison of colors; for confirmation of positive findings gradient HPTLC (AMD) followed by densitometric evaluation). 2. Analysis of important phospholipids in physiological chemistry (HPTLC of phospholipids on silica using a 25-step AMD gradient). 3. Analysis of medicinal plant ingredients due to growing legal requirements (HPTLC of hypericin on silica with ethyl acetate - formic acid - water 20:2:1; derivatization by immersion in 1% aluminium chloride solution and drying; densitometry at 436/> 560 nm (fluorescence)). 4. Content uniformity tests which are required by all modern pharmacopoeias (HPTLC of diclofenac-Na (Voltaren) on silica with toluene - ethyl acetate - acetic acid 60:10:1; quantification at 279 nm (absorbance).) Conclusions: Planar chromatography can be a very fast method offering relative low operating costs. In case of insufficient chromatographic separation gradient elution (AMD) may enhance it significantly. The method is robust with respect to matrix content. Post-chromatographic derivatization facilitates detection and quantification.

      Characterization of some chemically modified acidic alumina T samples for TLC
      M. FILIP, Virginia COMAN*, R. GRECU, K. Albert, Z. MOLDOVAN (*`Raluca Ripan’ Institute for Research in Chemistry, 30 Fantanele Street, P. O. Box 702, RO-400294 Cluj-Napoca, Romania)

      J. Planar Chromatogr. 17, 424-430 (2004). Chemically modified acidic alumina T stationary phases have been prepared by organosilylation with the trifunctional organosilicon compounds n-octadecyltrichlorosilane, 3-mercaptopropyltrimethylsilane, and N-(2-aminomethyl)-3-aminopropyltrimethoxysilane. These chemically modified phases were characterized by elemental analysis, measurement of specific surface area, FTIR spectroscopy, 13C CP/MAS NMR spectroscopy, mass spectroscopy, and thermal analysis. The TLC behavior has been tested by separation and identification of some dyes and benzo[a]pyrene derivatives.
