Abstract
Description
Способ хроматографического анализа вещества относится к методам разделения смесей веществ и предназначен для их анализа. Эти методы, как правило, основаны на распределении веществ в хроматографической колонке между двумя фазами - неподвижной (сорбентом) и подвижной (эльюентом).The method of chromatographic analysis of a substance relates to methods for separating mixtures of substances and is intended for their analysis. These methods, as a rule, are based on the distribution of substances in a chromatographic column between two phases - stationary (sorbent) and mobile (eluent).
Но известны и другие методы хроматографического анализа веществ, например, основанные на звуковом или акустическом разделении веществ (Патент США №4280823, МПК B01D 51/08, 1981 и заявка Великобритании №2059796, МПК B01D 51/08, 1981). Звуковые колебания распространяют вдоль хроматографической колонки.But there are other known methods of chromatographic analysis of substances, for example, based on sound or acoustic separation of substances (US Patent No. 4280823, IPC B01D 51/08, 1981 and UK application No. 2059796, IPC B01D 51/08, 1981). Sound vibrations propagate along the chromatographic column.
Наиболее близким к патентуемому способу является способ хроматографического анализа веществ, заключающийся в воздействии звуковыми (акустическими) колебаниями на разделяемую смесь веществ, проносимых газом (носителем) через хроматографическую колонку (Патент РФ №2156457, МПК7 G01N 30/00, оп. 20.09.2000).Closest to the patented method is a method of chromatographic analysis of substances, which consists in exposure to sound (acoustic) vibrations on a shared mixture of substances carried by a gas (carrier) through a chromatographic column (RF Patent No. 2156457, IPC7 G01N 30/00, op. 20.09.2000) .
Новый способ также заключается в воздействии звуковыми колебаниями на разделяемую смесь веществ, проносимых газом (носителем) через хроматографическую колонку.The new method also consists in the action of sound vibrations on the shared mixture of substances carried by a gas (carrier) through a chromatographic column.
Новым в нем является то, что на стенки хроматографической колонки до анализа наносят жидкий нематический кристалл, молекулы которого ориентируют поперек распространения звуковых колебаний.New in it is that before the analysis, a liquid nematic crystal is applied to the walls of the chromatographic column, the molecules of which are oriented across the propagation of sound vibrations.
На чертеже показана схема реализации способа. На нем изображена хроматографическая колонка 1 круглого сечения, на стенках которой радиально расположены продолговатые молекулы нематика 2, которые перпендикулярны вдоль колонки направленным акустическим волнам 3.The drawing shows a diagram of the implementation of the method. It depicts a chromatographic column 1 of circular cross section, on the walls of which are elongated molecules of nematic 2 radially located, which are perpendicular to the directional acoustic waves 3 along the column.
Молекулы нематика 2, будучи прикрепленными радиально к окружной стенке хроматографической колонки 1 и, следовательно, ориентированными поперек движения компонентов смеси веществ в потоке носителя через хроматографическую колонку 1 и разделяемые акустическими волнами 3, своими свободными концами цепляют проходящие мимо молекулы веществ в разной степени в соответствии со свойствами веществ, различными у различных веществ, дополнительно разделяются, что и повышает эффективность разделения.Molecules of nematic 2, being attached radially to the circumferential wall of the chromatographic column 1 and, therefore, oriented transversely to the movement of the components of the mixture of substances in the carrier stream through the chromatographic column 1 and separated by acoustic waves 3, cling to the free molecules of the substances passing by to different degrees according to properties of substances that are different for different substances are additionally separated, which increases the separation efficiency.
Техническим результатом нового способа хроматографического анализа вещества является повышение эффективности разделения звуковыми волнами анализируемой смеси веществ на компоненты.The technical result of the new method of chromatographic analysis of a substance is to increase the efficiency of separation of the analyzed mixture of substances into components by sound waves.
