      High pressure thin-layer chromatography on 3 micron spherical particle beads
      G. FLODBERG, J. ROERAADE, (Dept. of Anal. Chem., Royal Inst. of Techn., S-100044 Stockholm, Sweden)

      J. Planar Chromatogr. 6, 252-255 (1993). Comparison of the chromatographic performance of TLC plates coated with 3 µm spherical and 5 µm angular particles using a newly designed apparatus suitable for high pressure (>100 bar) OPLC. The best HETP values obtained were 17.3 and 34.2 µm particles, respectively. These high values were probably caused by the large particle size distribution. The problem of the comparatively low mechanical stability of the 3 µm layers (on glass plates) was solved by using a stainless steel membrane.

      Study of the hydrolytic cleavage of alkyl ligands from the surface of chemically bonded stationary phases by means of selected analytical techniques
      G. KOWALIK, T. KOWALSKA*, (*Inst. of Chem., Silesian Univ., 9 Szkolna Street, 40-006 Katowice, Poland)

      J. Planar Chromatogr. 14, 224-233 (2001). Review of findings on the susceptibility of the organic chemically bonded ligands to hydrolytic cleavage from the silica matrix for the most common TLC-type stationary phases, i.e. RP-18, RP-8, CN and DIOL. This process was induced by repeated (i.e. one-, two-, four-, and eightfold) development of these phases with mixed mobile phases comprising methanol, water, and buffers of different pH. Quantification of the extent of hydrolytic cleavage of the different ligands from the silica gel surface was basically achieved by means of Raman spectroscopy, although other analytical techniques like elemental (combustion) analysis, thermogravimetry, and differential scanning calorimetry were also employed. Also investigation of the factors influencing the efficiency of the hydrolytic cleavage.

      Some technical problems of application of solutes on chromatographic plates in TLC
      J.K. ROZYLO, G. BEREZKIN, I. MALINOWSKA, A. JAMROZEK-MANKO, (M. Curie-Sklodowska Univ., Fac. of Chem., Lublin, Poland)

      Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 127-136. Examination of the influence of the application method of samples on the migration of their components, dimension of spots on the developed chromatogram, resolution and the number of HETP. TLC of a standard mixture of dyes on silica gel with toluene. A new method of application is the use of a filter paper: A given volume of solute is applied on the filter paper - in the form of a triangle - using a calibrated micropipette, then by means of the mobile phase the solute is transferred from the filter to the sorbent layer.
