TL;DR: In this paper, the chromatographic characteristics of nine primary aliphatic amines have been studied using soap thin-layer chromatography, and the influence of the type of detergent and its concentration, of the organic solvent and of acid concentration on the behavior of these amines was investigated.

TL;DR: Alginic acid is proposed as a new stationary phase for TLC in this article, and the effects of the distance moved by the solvent front, temperature, hydrogen ion concentration of the eluents and the thickness of the layers on the R F values of some common elements have been extensively investigated.

TL;DR: Using soap thin-layer chromatography, the authors investigated the behavior of sulphonamides and primary aromatic amines in the presence and absence of acids, and the apparent pH of the eluent.

TL;DR: In this paper, the chromatographic behavior of 38 peptides on layers of silanized silica gel alone and impregnated with anionic and cationic detergents has been investigated.

TL;DR: In this article, the electrochemical behavior of aniline in aqueous alkaline solutions on smooth platinum, platinized platinum, graphite, and gold electrodes has been investigated.
