FIELD: analytic devices. SUBSTANCE: electric thermograph has flow reaction measurement cell in which duct wire catalytic pickup is mounted and placed in series in closed circuit with source of electric current and unit measuring volt-ampere characteristic of catalytic pickup. Reaction measurement cell is positioned inside case of ionization chamber of mass spectrometer composed of ion source and system of reagent leak-in. One end of reaction measurement cell is used as inlet for flows of reacting gases, is fixed tight on wall of case of ionization chamber and is connected to system of reagent leak-in, the other end of reaction measurement cell is used as outlet for products of investigated catalytic reaction, is located inside ionization chamber and is connected to inlet of ion source. EFFECT: possibility of chemical identification of emission flow. 4 dwg
