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. All
modules of the highest level (the modules are made in shells 2 on the
drawing) are grouped in the uniform hexagonally packed structure (on the
drawing it is surrounded with an external protective shell 3), produced
by their joint drawing in the softened condition.The method of columns
manufacturing consists in realization of several stages drawing of blanks
packages, each of which is drawing result at the previous stage, and
cuttings produced at drawing items on a part of the specified
length--blanks.The micrometer and submicrometer size of channels are
achieved at their number equal 1 million in order of magnitude with small
dispersion of the channel diameters.
