METHOD OF OBTAINING GAS-LIQUID-SOLID-PHASE MICROCHROMATOGRAPHIC COLUMNS ON SILICON PLATES AND DEVICE FOR THEREOF REALISATION Russian patent published in 2015 - IPC G01N30/56 

FIELD: chemistry.

SUBSTANCE: in method portions of solid carrier, dispersed in volatile dispersion medium, are periodically sprayed on the surface of silicon plate with preliminarily etched channels for microchromatographic column in form of aerosol in inert gas, with the following sealing by anode bonding of silicon plate with Pyrax brand glass. After that, immobile liquid phase in form of aerosol in inert gas is applied on the surface of solid carrier. Device for method realisation contains successively connected balloon with inert gas, unit for gas preparation, two thermostatically controlled tanks with solution of immobile liquid phase and solid carrier suspension, pulveriser, switching tap and special bubbler with regulated pneumoresistor at the output.

EFFECT: increased efficiency and separating ability of gas-liquid-solid-phase microchromatographic columns on silicon plates.
