FIELD: physics.
SUBSTANCE: invention relates to gas analysis and can be used for sample introduction into analysers of composition of environmental objects, food products, perfume and construction materials. Device for sample introduction into analyser of composition includes sorption tube with heater, focusing trap with cooling and heating system, tap-switch, gas regulators and valves for directing gas flows, characterized by that at the outlet of the trap there is a tee for dividing the sample stream into an analyser and for discharge.
EFFECT: simplification of design, elimination of overload of chromatographic column with large volume of sample, high reliability of analysis results.
