FIELD: chemistry.
SUBSTANCE: device for analysing impurity substances in a gas has a container for preparing samples for analysis. The device also has a channel carrying the analysed gas into the container which is fitted with a controlled check valve and a channel carrying atmospheric air into the container which is fitted with an absorbent filter for impurities in the air. The device also has a gas-flow detector for controlling content of impurities of the analysed substances in the container, which is fitted with a flow activator and joined to the container by connecting pipes. The device also has a vacuum pump connected through a receiver and a controlled check valve to the container, a ventilator fitted in the container and a pressure metre. The channel carrying cleaned atmospheric air into the container is fitted with a controlled check valve.
EFFECT: high accuracy of analysing gases.
