FIELD: tobacco industry.

SUBSTANCE: invention is related to tobacco industry and intended for usage in research laboratories. The installation for hookah smoke gas phase sampling consists of four separate lines linked in a single spot by means of connective tubes. The first line includes a hookah and a cut-off valve. The second line includes a discharging compressor, a gas meter measuring the preset volume puffing, a rotameter controlling volumetric flow rate of gases, a cut-off valve providing to puffing and a control valve for setting the preset volumetric flow rate. The third line consists of a reservoir for accumulation of gases and their displacement with water, a gauge container for draining water from the reservoir and two valves for filling the reservoir with water and draining. The fourth line contains a tight bag for gas sampling with a shutdown valve and a filter for clearing smoke of solid-and-liquid phase.
