FIELD: measurement technology.
SUBSTANCE: invention relates to micro-monitoring system and device. System for analyzing at least one chemical compound in a gas mixture, comprising: a sampling inlet; filter; trap; chromatographic column; detector; and a pump, wherein the sampling inlet, trap and pump are fluidly connected to form a first gas flow path in which the pump is located below the sampling inlet and trap in the flow direction, wherein the sampling inlet, filter, trap, chromatographic column, detector and pump are fluidly connected to form a second gas flow path in which the pump is located below all said components downstream, wherein the gas mixture is air.
EFFECT: technical result is high efficiency of determining organic compounds in gaseous media without use of compressed gas.
