      The influence of pH on retention and migration of peptides in systems with octadecyl silica-based adsorbent by high-performance thin-layer chromatography and pressurized planar electrochromatography techniques
      R.Ł. GWARDA, T.H. DZIDO* (*Dep. of Phys. Chem., Chair of Chem., Fac. of Pharm. with Med. Anal. Div., Med. Univ. of Lublin, 4a Chodźki St., 20-093 Lublin, Poland)
      J. Chromatogr. A 1534, 179-187 (2018). Investigation of the influence of pH of the mobile phase buffer on retention of peptides in both normal phase (NP) and reversed phase (RP) HPTLC systems with C18 silica-based adsorbent as the solid phase. Comparison of the influence of pH on retention and/or migration distance of peptides in separation systems of HPTLC and pressurized planar electrochromatography (PPEC) techniques. It was found that the change of pH of the mobile phase buffer can be used for two-dimensional HPTLC separation of peptides, but much stronger change of separation selectivity can be achieved by overall inversion of separation system type (NP/RP). Influence of the mobile phase pH on selectivity of peptide separation in PPEC is different than that in HPTLC, due to the significant share of electrophoretic effect in mechanism of separation and better selectivity of separation by PPEC, however the change of pH affects the efficiency of the separation system in both techniques, so it can be used for optimization of separation conditions. Discussion of some modifications of PPEC equipment and materials useful for application of this technique in the field of peptide analysis.
