Abstract: Polycapillary chromatographic column contains a set of parallel channels isolated from each other, walls of the channels on the inside are covered with sorbent, and are joined with walls of adjacent channels on the outside by fusing. Feature of a column is that it is produced as set of modules of a various level, thus the module of the lowest level represents hexagonally packed and having in cross-section shape of a correct hexagon set of the channels which are produced by joint drawing of a bundle of monocapillaries in the softened condition. The module of each higher level represents hexagonally packed and having in cross-section shape of a correct hexagon set of modules of the previous level, growing out by their joint drawing in the softened condition.
