THE APPLICATION OF LIQUID-CRYSTALS TO THE QUANTITATIVE-DETERMINATION OF ORGANIC-COMPOUNDS

The results are presented of studies on the possibilities of using liq uid crystals to perform quantitative determinations of organic compoun ds separated by TLC. Experiments have shown that the clearing points o f nematic binary mixtures of the liquid crystal and the substances bei ng determined varies linearly with the concentrations of the analytes and that this behavior may be used far quantitative determination: qua ntitative analysis reduces to simple measurement of the temperature at which the spot of the substance to be determined appears as mapped on a liquid crystalline detector.
