J. Liquid Chromatogr. 12, 979-985 (1989). TLC of some carboxy and hydroxy benzene derivatives related to lignin and humic materials on silica and Fe(III)- impregnated silica with 1) ethyl acetate, 2) ethyl acetate – benzene 9:11 and 3) ethyl acetate – benzene 5:15. Identification of the compounds tested by the mobility differences on impregnated and plain plates.
1. Effect of temperature on Rf values.) (Japanese). Kagaku to Kyoiku (Jap. J. Educ.) 42, 206-210 (1994). Examination of the effects of temperature on Rf values in TLC, with some dyes and simple organic compounds, e.g. nitrobenzene, phenol, etc., and steroids as analytes.
CBS 81, 10-12 (1998). A number of applications of HPTLC in the bulk drug industry are presented: process optimization, fermentation process monitoring, impurity profile, vessel residue certification and bulk drug analysis. The technique is advantageous when a large number of similar samples is to be analyzed and time and cost considerations are of importance.
Acta Chrom. 6, 21-38 (1996). The possibility of using a thermodynamic approach for optimization of mixed mobile phases for systems with binary and ternary solvents is discussed, as well as the method for predicting separation results in column liquid chromatography on the basis of experimental thin-layer chromatographic data. The effect of mobile phase composition on solute retention is described by solute capacity factors (characteristic of the pure solvents), molecular interactions occurring in the bulk phase and adsorption equilibrium in a given adsorbent – binary solution system. Two kinds of chambers were used in the investigation: a saturated Stahl chamber and a sandwich chamber. The study described the use of different TLC techniques as pilot methods for HPLC.
J. High Resol. Chromatogr. 9, 285-288 (1986). Presentation and discussion of equations for predicting analysis time in thin-layer chromatography as a function of spot separation, solvent velocity constant, DELTA Rf and Rf
J. Planar Chromatogr. 4, 439-441 (1991). Study of the effect on the retention behavior of some steroidal test solutes of pretreating the silica surface with the vapors of a variety of polar solvents and comparison with those obtained on untreated silica gel. Calculation of the slopes and intercepts of the linear relationships between the retention constant (RM) and the logarithm of the volume fraction of ethyl acetate and discussion in relation to the characteristics of the solute, and the mobile and stationary phase.
J. Planar Chromatogr. 11, 350-352 (1998). Attempt to use a theoretical equation - so far applied to adsorption chromatography - in reversed-phase systems with two-component mobile phases. The four-parameter equation is based on an adsorption-partition mechanism for the chromatographic process. Agreement between theoretical and experimental retention was found to be good over the whole range of mobile phase concentrations investigated. HPTLC of phenol, ethylbenzene, 4-chlorotoluene, nitrobenzene, naphthalene, biphenyl, naphthol on RP-18 with water - methanol mixtures with methanol molar fractions of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9.and 1.0. Densitometry at 285, 260 and 225 nm, respectively.
Comparison with results obtained by use of computational algorithms J. Planar Chromatogr. 22, 327-331 (2009) TLC of 27 novel imidazo[2,1-c][1,2,4]triazine derivatives together with 12 compounds with known literature log P values (as reference calibration data) on RP-18 with methanol - water binary mobile phases containing different proportions of methanol in horizontal chambers without chamber saturation. Detection under UV 254 nm. Using principal-component analysis the obtained results were compared with results from nine computational methods.
