FIELD: capillary gas chromatography. SUBSTANCE: device includes stabilizer of flow rate of auxiliary gas mixed with carrier gas, vortex generator of flow of gas mixture connected to heat flowmeter coupled to measuring and reading units. Pipe union to supply carrier gas is connected via variable laminar throttle to line feeding carrier gas and unit for injection of sample to which chromatographic column is joined. Resistance of laminar throttle equals that of chromatographic column or differs from it by known number of times. EFFECT: provision for measurement of small flow rates of carrier gas right in the course of chromatographic analysis without disconnection of capillary column from detector. 1 dwg
