J. Chromatogr. A 1170 (1-2), 91-100 (2007). Use of three modes of sample application on the chromatographic plate at present investigations of pressurized planar electrochromatography (PPEC) systems taking into special attention their influence on performance of the separating system: 1) application directly with microsyringe, 2) deposition of sample solution on scrap of adsorbent layer followed by location of this scrap on the chromatographic plate, 3) application with a commercially available aerosol applicator. All three modes were combined with prewetting of the chromatographic plates in order to accomplish equilibration of the stationary phase - mobile phase system. Best results were obtained when the plate was prewetted and when application was performed with commercially available aerosol applicator.
J. Planar Chromatogr. 12, 373-377 (1999). Development and evaluation of a new TLC manual multi-applicator for simultaneous deposition of up to 15 samples, successively on several plates of different sizes. Acepromethazine was used as test analyte, and plates were scanned at 375 nm. The multi-applicator furnished good inter-capillary reproducibility (relative standard deviation smaller or equal 4 %) and quantitatively satisfactory linearity (r = 0.996) and reproducibility (RSD = 4 %). HPTLC of acepromethazine maleate on silica gel with methanol. Quantitation by densitometry at 375 nm in absorbance mode.
J. Chromatogr. A 1218 (19), 2692-2699 (2011). HPTLC coupled with bioluminescence detection can be used for screening for unknown substances. So far the HPTLC plate was dipped in an aqueous solution of Vibrio fischeri bacteria. However polar substances may be dissolved during this process, which leads to blurring and tailing of the zones on the plate. This was overcome by application of the bacteria solution by rolling. A rolling device was made of commercially available household articles and tested using octhilinone and methylparaben. Comparison of rolling with dipping showed that despite the manual steps involved in the rolling process, the results were reproducible. Depending on the substance and its amount on the HPTLC plate, with rolling peaks were narrower, up to a factor of 4 higher and showed a higher signal-to-noise ratio than with dipping.
J. Planar Chromatogr. 13, 82-87 (2000). Description of the possibility of applying mixtures of substances to TLC plates by use of different types of filter (chromatographic) paper as concentrating zones. The resolution of achromatographic systems has been compared after use of different modes of solute application - applicator (point and linear application), micropipet, use of plates with concentrating zone, and use of different filter papers as concentrating zone. The proposed use of paper as a concentrating zone increases the resolution of a chromatographic system compared with a micropipet; resolution is comparable with that obtained on commercially available plates with concentrating zones.
J. Liq. Chromatogr. Relat. Technol. 36, 2512-2523 (2013). The paper described the influence of several operating variables of online injection into the pressurized planar electrochromatography (PPEC) separation system. Variables that enable narrow and symmetrical peaks such as sample volume, flow velocity, shapes of the grooves and polarization potential were discussed.
J. Planar Chromatogr. 12, 373-377 (1999). Description of a new multi-applicator for simultaneous deposition of up to 15 samples, successively on several plates of different sizes. Acepromethazine was used as test analyte, and plates were scanned at 375 nm. The multi-applicator furnished reliable results, both qualitatively - good inter-capillary reproducibility, and adaptibility - and quantitatively - satisfactory linearity, reproducibility, correlation with an autosampler.
GIT Suppl. Chromatogr. 3, 32-38 (1986); part II: GIT Fachz. Lab. 10, 993-998, (1986). Principle and applicability of TLC using mobile phase pressure of up to 80 bars. Circular development of single sample injected in-flow and of multi samples applied on the dry layer. Use of normal and reversed phase material, including multiple use of the same layer. Quantification of the chromatograms by direct image processing using optical sensitive RAM.
J. Planar Chromatogr. 13, 470-472 (2000). Evaluation of the application of new materials (both chromatography and filter paper) as the concentrating zone; evaluation of the possibility of combining paper and TLC on a flexible support; and realization of a simple variant of the technique (paper and TLC plate) which would enable realization of the technique in any laboratory. TLC of methyl orange, methyl red and methyl green (0.1% in ethanol) with ethanol as mobile phase on silica gel with concentrating zone and Sorbfil polymer resp. on silica gel with chromatography paper instead of the concentrating zone.
