GAS ANALYSER Russian patent published in 2010 - IPC G01N27/64 

FIELD: physics.

SUBSTANCE: gas analyser has a measuring chamber with lines for inlet and outlet of the analysed gas, two flow activators, as well as mixer-container of given volume mounted in the line carrying the analysed gas into the measuring chamber of the detector. A filter-absorber is installed in the line carrying the analysed gas from the measuring chamber of the gas detector. The gas analyser can also include a device for measuring gas flow fitted in the line carrying the analysed gas from the measuring chamber. Also at least one flow activator can be made in form of a gas syringe in the cylindrical body of which a piston with a plunger if put with possibility of back-and-forth movement.

EFFECT: measurement of high concentrations of different substances in air and possibility of periodically cleaning the measuring chamber, avoiding contact between the highly concentrated substance and the surface of the detector.
