description FIELD: analytical instrumentation engineering; photoionization gas analyzers built around ultraviolet lamps. ^ SUBSTANCE: proposed ultraviolet lamp has sealed body filled with gas mixture emitting in vacuum ultraviolet region and device for striking discharge within lamp. Lamp body accommodates heating element designed for heating light outlet window. Photoionization gas analyzer has ionization chamber with pipe union for feeding gas (air) being analyzed, ionization source in the form of ultraviolet lamp, electrodes installed within ionization chamber, and microprocessor used for processing signal being measured and for monitoring gas analyzer in operation. Heating element used for heating lamp window is made in the form of resistor disposed near lamp window or directly on inner surface of window; it also has temperature sensors of which one is disposed on lamp window surface, and temperature sensors are installed outside ionization chamber case. ^ EFFECT: reduced power requirement and size of lamp. ^ 4 cl, 4 dwg
