FIELD: process engineering.
SUBSTANCE: invention relates to micro jet device for molecular scattering or for detection of preset substance in liquid sample. Proposed device comprise first substrate with, in fact, flat first surface formed by first cutouts and second substrate with, in fact, second flat surface formed by second cutouts. Part of said first cutouts is filled with porous material. Alternating first and second cutouts make zigzag channel for liquid sample. Second cutouts may be filled with another porous material. In compliance with one version, trapping substance is arranged in or on porous material to bind preset substance.
EFFECT: higher pressures and flow rates of specimen fluid.
