      Sensitive fluorescent quantitation of myo-inositol 1,2-cyclic phosphate and myo-inositol 1-phosphate by high-performance thin-layer chromatography
      K.K. HEDBERG, B. COGAN, G.B. BIRRELL, O.H. GRIFFITH*, (*Inst. Mol. Biol. & Dep. Chem., Univ. Oregon, Eugene, OR 97403, USA)

      J. Chromatogr. B, 757 (2), 317-324 (2001). Description of a non-radioactive micro-assay for the cyclic phosphodiesterase reaction catalyzed by Bacillus cereus phosphatidylinositol-specific phospholipase C, involving HPTLC on silica gel to resolve the substrate (myo-inositol 1,2-cyclic phosphate and the product (myo-inositol 1-phosphate), followed by detection with a lead tetraacetate-fluorescein stain. Quantitation by analysis of the fluorescent plate image with a commercial phosphoimager and associated software, for sample in the rage of 0.1 to 50 nmol.

      Polarity-adjustable reversed phase ultrathin-layer chromatography
      J.Z. HALL, M.T. TASCHUK, M.J. BRETT* (*Dep. Electr. & Comp. Engin., Univ. of Alberta, 2nd Floor ECERF, Edmonton, Alberta T6G 2V4, Canada)

      J. Chromatogr. A 1266, 168-174 (2012). RP-TLC plates modified with C18, C8 or C2 are available on the market, however, RP-plates with tunable polarity have not been reported. Because of the limited variety of RP-plates mobile phase optimization is needed which is often time consuming. The presented polarity-adjustable RP-UTLC plates simplify the mobile phase screening process and expand the selection of reversed phase plates. The plates were prepared using the glancing angle deposition (GLAD) technique to deposit SiO2 nanopillars on glass plates and functionalized with octadecyltrichlorosilane for hydrophobicity. By O2 plasma treatment the silane carbon chain was shortened and COOH groups were introduced to the surface, producing plates with finely tunable polarities. Confirmation of the tuning of surface polarities by measurement of retention behavior changes in the separation of a model dye mixture of Sudan blue and Sudan IV, the elution order of which reversed as a result of the change in surface polarity. Testing on commercial RP-plates showed no change in the separation behavior which proves that plasma treatment of GLAD structures with highly accessible surfaces improves control over interfacial properties, producing better reverse phase separations. UTLC of Sudan blue and Sudan IV in toluene on the new RP-UTLC plates in horizontal developing chamber with acetonitrile, detection in visual light by recording of the development process by video camera).

      J. Planar Chromatogr. 31, 36-47 (2018). Mineralogical and physicochemical characterization of the Nevşehir tuff and its application as a stationary phase for the separation of polar compounds such as amino acids or food dyes. Plates were coated with a slurry consisting of a mixture of adsorbent (Mirșid tuff or_x000D_ Nevşehir tuff), binder (polyvinyl alcohol or gypsum), and other admixtures. The impregnation of the Nevşehir tuff with sodium hydroxide and sodium chloride, respectively, allowed the separation of some hydrophilic dyes.

      J. Planar Chromatogr. 3, 331-335 (1990). A new version of Empore TLC sheets (silica of chemically bonded silica particles of 8 µm mean particle size enmeshed in a network of polytetrafluoroethylene fibrils) is shown to have improved separation speed and efficiency compared with earlier versions of the material. Its separation performance is comparable with that of conventional TLC layers. Successful use in scanning densitometry and forced flow development is also demonstrated.
