Abstract: Electric field influence on the chromatographic behaviour of polar compounds and their mixes on the filled column with a 4-metoxy-4${}^{'}$-etoxyazoxybenzene liquid crystal sorbent are studied. It is established that under the influence of electric field there is an irreversible adsorption of molecule of polar sorbates on interphase borders of a sorbent that leads to a delay of a substance test part and area reduction of chromatographic peak. It is shown that on a short column with a liquid crystal sorbent influenced by electric field, it is possible to carry out quantitative analysis of not divided components of mixes which give the blocked peaks on the chromatogram.

Keywords: gas chromatography, liquid crystal sorbents, electric field influence, the quantitative analysis.
