Anal. Biochem. 188, 5-8 (1990). TLC of glycosphingolipids on silica with a) chloroform - methanol - 120:70:17 containing 0.02% CaCl2. Detection by immunochemical method involving oxidation of diol groups of compounds with sodium peroxide, derivatization of formed aldehyde groups with an alkaline phosphatase-labeled polyclonal anti-digoxigenin antibody. Detection of the latter by an insoluble indigo-like dye as a result of dephosphorylation of 5-bromo-4-chloro-3-indolyl phosphate. Discussion of the detectability of all glycosphingolipid species.

Part III: Effect of solvent polarity on the selectivity of nitromethane for discriminating between alternant versus non alternant polycyclic aromatic hydrocarbons. Appl. Spectrosc. 47, 715-722 (1993). Investigation of the effect on the fluorescence emission behavior of 96 different polycyclic aromatic hydrocarbons (PAHs) dissolved in binary toluene/acetonitrile solvent mixtures, to better assess the applicability of nitromethane as a selective quenching agent for alternant versus non alternant PAHs in TLC, as well as in HPLC. Discussion of the results which revealed that the "selective quenching" rule is obeyed for the majority of PAHs.

J. of Chromatogr. A 1218 (19), 2820-2825 (2011). A unified procedure for image preprocessing of 2D TLC videoscans saved as JPG files is proposed for further supervised or unsupervised chemometric analysis. The procedure was based on open source software and included denoising using a median filter, baseline removal with the rollerball algorithm and nonlinear warping using spline functions. The application of the proposed procedure enabled filtration of random differences between images, such as changes in the intensity of the background as well as differences in the location of the zones. After the preprocessing only the zone intensity had an influence on the statistical analysis by principal component analysis (PCA) or other techniques. The proposed technique was successfully applied for the determination of the differences between three Carex species based on the 2D videoscans of the extracts.
