Abstract
Способ анализа оптических и структурных изомеров путем разделения анализируемой смеси на композиционном жидкокристаллическом сорбенте, содержащем смектико-нематический жидкий кристалл 4-н-октилокси-4'-цианобифенил и хиральный макроциклический модифицированный β-циклодекстрин, с последующим определением характеристик удерживания исследуемых веществ по результатам измерения хроматографических сигналов из полученных хроматограмм, отличающийся тем, что в качестве хиральной макроциклической добавки используют модифицированный β-циклодекстрин-(гептакис-2,3,6-О-ацетил)-β-циклодекстрин в количестве 10% от массы жидкого кристалла. A method for analyzing optical and structural isomers by separating the analyzed mixture on a composite liquid crystal sorbent containing a smectic-nematic liquid crystal of 4-n-octyloxy-4'-cyanobiphenyl and a chiral macrocyclic modified β-cyclodextrin, followed by determination of the retention characteristics of the studied substances according to the results of chromatographic measurements signals from the obtained chromatograms, characterized in that modified β-qi is used as a chiral macrocyclic additive lodekstrin- (heptakis-2,3,6-O-acetyl) -β-cyclodextrin in an amount of 10% by weight of the liquid crystal.
