FIELD: gas analysis. SUBSTANCE: device taking and injecting samples can be used in combination with gas chromatograph to check level of pollution of environment. It includes sampling line communicating with inlet to analyzed atmosphere, intermediate chamber linked with outlet to pump and line injecting sample into analyzer connected in sequence through flow limiters. Intermediate chamber and line injecting sample are joined with inlets to source of carrier gas through valves. Flow limiter is installed in line of carrier gas that connects line injecting sample to source of carrier gas. Sampling line is linked with outlet to pump. EFFECT: provision for high reproducibility of analysis. 4 cl, 2 dwg
