J. Liq. Chromatogr. Relat. Technol. 43, 300-304 (2020). HPTLC of thymol, carvacrol and linalool in Solidago canadensis on silica gel with n-hexane - acetone 4:1. The method was compared with bilateral band compression (BBC) of the 10 mm wide lanes of HPTLC separation, resulting in more than 6 times increase in peak height and peak area. In BBC a solvent flow perpendicular to the direction of chromatogram development squeezes the chromatographic bands into a smaller area The method improved detection sensitivity of sample components with low abundance.
Biomed. Chromatogr. 21 (10), 1064-1068 (2007). Indirect chiral separation of penicillamine (3,3-dimethylcysteine) enantiomers after derivatization with Marfey's reagent (FDNP-Ala-NH2) and two of its structural variants, FDNP-Phe-NH2 and FDNP-Val-NH2, with phenol - water 3:1 and solvent combinations of acetonitrile and triethylamine phosphate buffer in normal and reversed-phase TLC, respectively. Also separation of the diastereomers on a reversed-phase HPLC column with gradient elution of acetonitrile and 0.01 m trifluoroacetic acid. Comparison of the results due to these three reagents. Successful application of the method for checking the enantiomeric impurity of l-penicillamine in d-penicillamine and to check the enantiomeric purity of pharmaceutical formulations of d-penicillamine.
J. Planar Chromatogr. 23, 382-395 (2010). The paper summarizes progress in the main forced-flow planar liquid chromatographic (FFPLC) techniques taking into account one group of FFPLC used in practice, OPLC and rotation planar chromatography and another group like e. g. electrochromatographic techniques and shear-driven chromatography which show interesting results at an experimental level. Progress in FFPLC deals with the diversity of further instrumental developments and its basis, the instrument developments, determination of the role of the adsorbent layer in OPLC, challenges in the OPLC instrument development, and analytical and preparative applications of OPLC. Centrifugal layer or rotation planar chromatography is mentioned briefly. Two electrochromatographic techniques have been developed to accelerate the mobile phase flow, planar electrochromatography and planar dielectrochromatography using direct and alternating currents, respectively. One of the newest techniques among FFPLC is shear-driven chromatography in which the mobile phase is between two plates and is forced to flow above and inside the very thin adsorbent layer with shear-driven force generated by a moving plate. For the study of the biological activity of natural and synthetic compounds the planar adsorbent layer is advantageous, namely for in-vitro and in-vivo studies.
J. Planar Chromatogr. 29, 77-81 (2016). Orthogonal pressurized planar electrochromatography (OPPEC) of 4-(2-pyridylazo)resorcinol monosodium salt (1), patent blue (2), and azorubine (3) on RP-18W with 45 % methanol in buffer solution (pH 3.2, final concentration of buffer components in the mobile phase: 2.28 mmol/L of citric acid and 1.34 mmol/L of disodium hydrogen phosphate). The external pressure exerted on the adsorbent layer was set up as 15.0 bar. The polarization voltage applied to the electrodes was 1.5 kV, and the separation time was 150 min.
Trends Anal. Chem. 108, 13-22 (2018). Review of the potential of 3D printing for the manufacturing of millifluidic platforms for analytical chemistry. Key features of 3D printed devices incorporating chromatographic/electrophoretic separation was summarized, including photopolymer inkjet printing in a planar chromatography format for the separation of visible dyes and fluorescently tagged proteins.
