FIELD: physical-chemical measurements, namely, devices for automatic analysis of gases. SUBSTANCE: pulse gas analyzer incorporates hydrogen detector, column coming in the form of tube connected to input of detector, switch of gas flows with drive, stabilizer of flow rate of analyzed gas which inlet is linked to line of analyzed gas and which outlet is connected to inlet channel of switch of gas flows and unit programming operation of switch of gas flows. Gas analyzer additionally includes filter cleaning analyzed gas from hydrogen and bypass line. Switch of gas flows is mounted for connection of inlet channel to one of two outlet channels. One outlet channel is linked to inlet of filter cleaning analyzed gas from hydrogen, another outlet channel is connected to inlet of bypass line. Outlets of filter and bypass line are interjoined and connected to inlet of column. EFFECT: development of pulse gas analyzer requiring no additional flow of carrier gas for measurements. 1 dwg
