Abstract (en)
[origin: WO2011161137A1] In a non-dispersive gas analyzer, comprising a light source (3), the light (6) of which shines through a measuring cuvette (1) containing a measuring gas to be analyzed onto a non-selective detector (7) having a downstream evaluation unit (8), a multi-component gas analysis is made possible using simple means in that the light source (3) is a flash discharge lamp (4) and the evaluation unit (8) is designed to evaluate the temporal pulse curves of the flash (9) shining onto the detector (8). The invention takes advantage of the property of flash discharge lamps in that the emitted wavelength components vary over the duration of the flash (6).
