FIELD: chemistry.
SUBSTANCE: channels for microchromatographic column are obtained on the surface of flat plate with their further sealing and filling with respective sorbent, with channels for microchromatographic column on flat plate being obtained by method of laser ablation, and flat plates being made of various metals, silicon, glass or polymers. In addition, sealing of microchromatographic column is carried out with glass plate through polymer film gasket under vacuum and impact of temperature.
EFFECT: extension of assortment of materials for manufacturing microchromatographic columns with application of laser ablation.
