FIELD: sampling apparatus. SUBSTANCE: this sample taking device can be used in chemical, metallurgical, oil refining, gas processing, construction branches of national economy for taking samples to be forwarded to automatic gas analyzers. Device is particularly suitable for industrial chromatography. Device has sample taking pipe connected with filter and trap, cooler connected by pipeline with sample taking line and compressed air source through switching valve, hydraulic seal connected by pipelines with trap and cooler, and valves installed in pipelines which connect hydraulic seal with trap and cooler. Device is additionally provided with pipeline which connects valves with line connecting cooler with switching valve. Valves are provided with pneumatic control spaces for connection with additional pipeline and throttling members for compressed air to flow through them. EFFECT: higher efficiency. 1 dwg
